Cell surface display elements, often called CSDs, act as molecular trafficking instructions. When genetically attached to an antigen or another protein, they can influence whether the resulting construct is correctly folded, transported through the secretory pathway and ultimately exposed on the outside of the cell. These processes involve passage through intracellular compartments such as the endoplasmic reticulum and Golgi apparatus, followed by delivery to the plasma membrane. A CSD that performs poorly may cause the antigen to remain inside the cell, become degraded or appear on the surface at levels too low to trigger an effective biological response. Conversely, a potent CSD can substantially increase the amount of antigen available for recognition by antibodies or engineered immune cells. Despite their importance, CSDs have generally been selected through trial and error rather than through a systematic sequence-based design framework.

To build that framework, Fang, Saskin, Lee and colleagues generated a large experimental dataset based on more than 570 chimeric antigens. In these constructs, different CSD sequences were connected to a common antigen or protein cargo, allowing the researchers to compare how strongly each sequence promoted surface localization. The team used these measurements to derive translocation-strength labels for approximately 310 CSD elements. These labels provided the central training signal for DeepSCan: instead of simply asking whether a protein reached the cell surface, the models were trained to estimate relative potency and distinguish weak, moderate and highly effective display elements. The researchers also assembled roughly 45 independent training datasets, creating a broader information base for model development and evaluation.

DeepSCan was developed through three generations of models, reflecting an iterative effort to improve prediction quality and experimental usefulness. Deep learning systems can examine patterns across biological sequences that are difficult to identify by manual inspection, including combinations of residues, spacing relationships and broader sequence features. In this context, the models were not merely searching for one universal motif. They were learning how different sequence architectures could influence membrane trafficking, secretion and surface retention. The goal was to capture conserved functional principles while allowing for diversity among effective CSDs. Such a strategy is particularly valuable because sequences with similar activity may not be obviously related at the level of simple alignments, while small changes in a functional trafficking signal can have large effects on the final amount of surface-displayed protein.

The researchers then used the models as design tools rather than as passive predictors. DeepSCan computationally generated approximately 3,700 candidate CSD sequences, expanding the search beyond the limited set of elements found in nature. Around 120 of these generative designs were experimentally tested. This experimental step was essential because computational scores cannot fully capture the complexity of a living cell. The performance of a CSD can depend on the identity of the attached antigen, the expression system, the cell type and the interaction between the engineered sequence and the host’s own trafficking machinery. By repeatedly moving between prediction and laboratory validation, the researchers were able to identify designs that retained strong activity under real biological conditions.

Seven generative CSDs ultimately matched or exceeded the cell surface translocation strength of the most potent naturally occurring elements examined in the study. The result suggests that sequence-based artificial intelligence can do more than classify existing biological parts: it can help create new modules with useful functions. The strongest designs are important not only because they increase display levels, but also because they may offer alternatives to naturally derived sequences that have limitations in size, compatibility or performance. In an engineering setting, having a larger library of potent CSDs could allow researchers to select elements optimized for different antigens and host cells instead of relying on a small collection of standard signals.

The study also examined whether the enhanced display effects were restricted to a single experimental context. According to the researchers, improved surface presentation was observed across multiple cell types, indicating that the best-performing elements were not entirely dependent on one cellular background. This kind of portability is a major consideration for therapeutic development. A trafficking signal that functions in one laboratory cell line may behave differently in primary immune cells or in cells used for manufacturing. Demonstrating activity across distinct cell types provides an early indication that the engineered CSDs could be useful in broader applications, although further testing would be required to establish their behavior in clinically relevant systems and in living organisms.

The researchers additionally tested the biological consequence of improved display in an antigen-specific CAR-T cytotoxicity assay. CAR-T cells are genetically engineered immune cells whose chimeric antigen receptors recognize a selected target and activate killing responses when that target is present. In this experiment, cells displaying antigens through enhanced CSDs were evaluated for their ability to stimulate antigen-specific CAR-T activity. Stronger surface presentation can increase the number of antigen molecules available for receptor engagement, potentially improving the clarity and strength of the immune-cell response. The assay therefore connected the molecular performance of the CSDs with a functional immune outcome, although it does not by itself establish therapeutic efficacy or safety.

DeepSCan could become a general platform for engineering cell-surface interfaces in vaccines, immunotherapies and synthetic biology. For mRNA antigen display, for example, a potent CSD could help direct newly produced antigen to the outer membrane of cells after delivery of the mRNA, where it could be more readily detected by immune receptors. The same principle could support screening systems, cellular biosensors and engineered tissues that need to present defined proteins externally. The study also illustrates a broader shift in biological design: large experimental datasets can be used to train models, models can propose new sequences, and laboratory testing can feed the results back into the next design cycle. The researchers’ findings suggest that this combination may turn cell surface trafficking from a largely empirical process into a more predictable engineering discipline, while underscoring the need for continued validation across cargos, cell types and disease-relevant settings.

Male pattern hair loss is a prevalent condition affecting a substantial portion of the male population worldwide. Traditionally characterized by a progressive thinning of hair on the crown and temples, the etiology of this condition remains largely elusive, despite its widespread occurrence. The contemporary diagnostic methodologies often rely on subjective assessments and visual inspections, which can lead to variability in diagnosis and treatment effectiveness. Recognizing the limitations of these methods, the research team sought to employ AI technologies to refine the stratification process and provide a more structured understanding of hair loss patterns.

The study’s foundation lies in advanced AI algorithms capable of processing complex datasets. By leveraging a vast array of data points, these machine learning models can discern patterns that may not be immediately noticeable to the human eye. The researchers focused on developing a system that analyzes the ratio of hair loss in specific regions of the scalp, mapping these areas to generate a comprehensive stratification framework. Such an approach holds the potential to revolutionize how clinicians diagnose and treat MPHL, transitioning from a purely visual assessment to a data-driven, algorithmically enhanced evaluation.

A critical aspect of the study revolves around the creation of a robust dataset derived from various demographic groups displaying diverse hair loss patterns. This extensive collection of information enabled the AI models to develop a nuanced understanding of the different stages of MPHL, taking into account factors such as age, ethnicity, and genetic predisposition. By using this rich tapestry of data, the researchers were able to validate and fine-tune their algorithms, ensuring that the final outputs were both accurate and clinically relevant.

The implementation of this innovative loss region ratio analysis allows for a multi-dimensional exploration of hair loss, turning three-dimensional scans of the scalp into the basis for sophisticated evaluations. The resulting stratification can inform treatment options, enabling personalized approaches for individuals. For instance, patients presenting with specific loss patterns may benefit from targeted therapies, such as minoxidil or finasteride, while others might require alternative interventions, including hair transplants or low-level laser therapy.

Furthermore, the implications of this research extend beyond mere diagnosis and treatment. With an improved understanding of hair loss patterns, pharmaceutical companies could tailor their drug developments to address the unique triggers and pathways pertinent to various subtypes of MPHL. This could accelerate the discovery of more effective therapeutics, paving the way for a future where male pattern hair loss is not only stoppable but potentially reversible.

The research team emphasizes the importance of continued collaboration between data scientists, clinicians, and industry stakeholders to ensure the viability of their findings in real-world applications. Investing in further studies and clinical trials will be imperative to corroborate the efficacy of AI-based stratification in larger populations. By doing so, the scientific community can build a comprehensive model for understanding hair loss that transcends traditional boundaries.

In addition to providing a clinical framework, this study contributes to the growing body of knowledge regarding the sociocultural implications of male pattern hair loss. The psychosocial burden experienced by men suffering from this condition is frequently overlooked; by improving diagnosis and treatment, the researchers hope to alleviate some of the stigma and self-esteem issues associated with hair loss. This could foster a more supportive environment for individuals to address their hair loss proactively rather than reactively.

Moreover, the introduction of this AI-driven stratification model could serve as a prototype for other areas of dermatology and beyond. By showcasing how advanced technologies can enhance the understanding of complex biological phenomena, the groundwork laid forth in this study may encourage similar innovative approaches in addressing other skin conditions, including alopecia areata, psoriasis, or eczema.

In conclusion, the application of AI through the lens of loss region ratio analysis signifies a pivotal evolution in the field of dermatology and has the potential to reshape the landscape of male pattern hair loss treatment. This research not only underscores the emerging capabilities of technology in enhancing human life quality but also invites further exploration into understanding the underlying complexities of hair loss.

The machine learning that powers such websites will scan millions of images on the internet, analyze them and assemble facets of them into fresh, but fake, images.

Now, University of Kansas researchers are working to use a similar machine-learning process to build new proteins designed to detect water pollutants. With a new three-year, $1.5 million grant from the National Science Foundation’s Molecular Foundations for Biotechnology program, a KU researcher will use machine learning to create “deep-fake” membrane beta-barrel proteins — a class of naturally successful biosensors — designed to detect polluting metal ions in water.

“These beta barrels are super useful because they can bring things across membranes,” said principal investigator Joanna Slusky, associate professor of molecular biosciences at KU. “Barrels make good enzymes — there are so many different things that barrels can do.”

Previous research on the tube-like beta barrels has altered their binding properties for a variety of tasks. However, much of this work was arduous and completed by hand, usually resulting with minor variations of a limited number of scaffolds, or barrel structures.

“In this case, we’re using machine learning to generate large numbers of barrels,” Slusky said. “But, how about if we can both generate barrels and have them be useful? We asked ourselves, ‘What’s a biotechnology application of barrels?’ Well, one would be metal sensors that could perhaps detect metal pollutants.”

Slusky and her co-principal investigators, professors Rachel Kolodny and Margarita Osadchy of Haifa University in Israel (along with KU postdoctoral fellow Daniel Montezano), will develop a new machine-learning process that generates beta-barrels with scaffolds similar to those found in nature, but with different sequences.

“There’s a website called ‘This X Does Not Exist,’” Slusky said. “If you go to that site, you see all these AI-generated things and people don’t really exist. But a computer made an image, for instance, of a cat. But that’s not really a cat — a computer took a bunch of pictures of cats and said, ‘OK, we can just sort of generate as many cat pictures as you want now, because we figured out what is a cat.’ We need to make something real so we see it more like generating a recipe.

“The question is, how to make computers generate a recipe for proteins.”

Beta barrels are well-suited to advancement through machine learning because “natural proteins are sort of a small blip in the number of possible sequences.”

If a computer algorithm can learn the essence of what makes a protein a protein, Slusky said, it will avoid generating useless sequences.

“Most sequences would never actually be proteins— they wouldn’t have a particular fold,” she said. “They would just kind of bond with themselves in weird, nonpredictable ways over and over again. To be a protein, you need a sequence that makes one shape. When people tried to make random sequences, or even somewhat directed sequences, they found that only a very, very small percentage of them might actually be a protein.”

With machine learning creating new and viable sequences resulting in this common fold, Slusky and her colleagues hope to generate a beta-barrel especially well-suited to finding metal ions in water. This result of the work will be biosensors based on beta barrels that can identify pollutants like lead in waterways.

“If we make them the right size, this molecule will be ideal to put some particular metal in, and you can have the right substituents so that it would bind that metal,” Slusky said. “Because it’s in a membrane, it can give you some sort of conductance difference — there’s a difference between when it’s bound and when it’s not bound. If you’re able to do that, you could sense for different metals, and different concentrations of those metals. There are a lot of big steps we want to accomplish, but I’m hopeful and excited.”

The work also will help train undergraduate researchers in Slusky’s lab, as well as inform Slusky’s teaching at KU as well as outreach to high-school science students.

At the core of S²ALM’s development lies a comprehensive understanding of the intricate relationship between an antibody’s amino acid sequence and its three-dimensional structure. As Professor Tingjun Hou eloquently stated, “The molecular basis of any antibody protein lies in its amino acid sequence. The sequence dictates its 3D structure, which subsequently determines its biological function.” This interplay between sequence and structure has often been overlooked in existing AI models, which predominantly fixate on sequence data alone. S²ALM breaks new ground by integrating both aspects, thus yielding a more nuanced and complete representation of antibody behavior and efficacy.

To train this state-of-the-art model, the researchers utilized an expansive dataset comprising an astonishing 75 million antibody sequences and 11.7 million three-dimensional structural representations. The structures included both results acquired through experimental means and those predicted computationally. This rich dataset enabled S²ALM to develop a deep understanding of the functional and structural paradigms governing antibody interactions, enhancing its predictive capabilities far beyond what has previously been achievable.

The researchers employed an innovative hierarchical pre-training strategy, which comprises two key learning objectives: Sequence-Structure Matching (SSM) and Cross-Level Reconstruction (CLR). SSM allows S²ALM to correlate sequence data with their corresponding structural contexts, effectively bridging the gap between the two. This strategy ensures that the model is not merely correlating patterns but is also capable of understanding the underlying connections that inform an antibody’s binding capacity. On the other hand, CLR empowers the model to foresee and reconstruct missing data by utilizing clues derived from both sequence and structure, enhancing its overall predictive accuracy.

The results of the study revealed that S²ALM significantly outperformed existing AI models across a myriad of essential tasks, including the prediction of antigen-binding capacities, the mapping of B cell maturation processes, and the identification of specific regions on antibodies known as paratopes. Perhaps most impressively, the model demonstrated an uncanny ability to design entirely new antibody sequences that could target formidable pathogens such as the SARS-CoV-2 virus, Ebola, and Influenza B. Such capabilities underscore the potential of S²ALM to not only facilitate the understanding of antibody functions but also expedite the design of effective therapeutic agents.
