Lecture Title: VUS.Life: Harnessing Vector Embeddings for Fast, Precise Pathogenicity Prediction of Genetic Variants

Interpreting pathogenicity of genetic variants, somatic or germline, in genes like BRCA1 and BRCA2 remains a major challenge in genomic medicine. Vector embeddings, key to the success of Large Language Models (LLMs), enable semantic representation of complex multimodal data. We created a framework for semantic vector representations of variants, excluding known pathogenicity assertions to avoid data leakage, that effectively captures nuanced relationships of variant features linked to pathogenicity. Our method enables automated classification with >97% accuracy using top models for genes evaluated. This framework therefore empowers precision medicine in prioritizing Variants of Uncertain Significance (VUS) for clinical review and evidence-based reclassification.

Lecture Title: Spatial transcriptomics on a diverse pancreatic cancer cohort reveals Black African Americans display reduced classical and increased intermediate tumor subtype

Abstract: Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy and is 20% more likely to develop in Black African American (BAA) patients, compared to Non-African American (NAA) patients. A comprehensive analysis of the large-scale gene expression signatures of tumor subtypes and cellular microenvironments of BAA PDAC versus NAA PDAC has not been rigorously evaluated. Here we present, for the first time, a multi-omics interrogation of BAA versus NAA PDAC using laser capture microdissection, spatial transcriptomics (ST), and 100-plex spatial proteomics platforms, with key findings verified by immunohistochemistry.  Whole-exome sequencing confirmed African genetic ancestry in the self-reported race of BAA samples. We analyzed 7 BAA and 15 NAA PDAC samples, combining our cohort with Human Tumor Atlas Network (HTAN) ST data. We found that BAA PDAC tumors exhibit a significant decrease in classical subtype cells, accompanied by no change in the aggressive basal-like subtype. Intriguingly, BAA patients show a significant enrichment of the intermediate/hybrid phenotype that co-expresses genes in both subtypes, as well as unique markers, compared to NAA PDAC. BAA PDAC tissues displayed increased B cell interactions and reduced myeloid cell presence, compared to NAA tumors. Our findings suggest BAA tumors show a shift toward intermediate subtypes and a distinct immune cell composition within the tumor microenvironment. This study highlights that health disparities in patients of different ancestry may have a molecular basis that influences tumor aggressiveness and the immune response that may inform therapeutic efficacy and options.

Lecture Title: Leveraging single-cell transcriptomics for bacterial functional genomics and deciphering viral interactions

Abstract: Even within the same species, bacteria differentiate into distinct phenotypic states. In a complex consortium such as the microbiota, in the presence of other species and predation by bacteriophages, diverse bacterial phenotypes contribute to community fitness and promote phage resistance. However, population-level gene expression measurements are insufficient to resolve such states. We have employed high-throughput bacterial single-cell RNA sequencing to resolve the progression of a lytic phage infection in a human pathobiont, Bacteroides fragilis. Using both host and viral transcriptomic data, we quantified the asynchronous progression of phage infection in individual bacterial cells and determined that each cell’s vulnerability to phage was influenced by variable expression of multiple genetic loci. Extending our analysis to human fecal microbiota, we quantified the heterogeneous phenotypic states in diverse species and associated them with bacteriophages. Finally, we demonstrate how the coupling of pooled CRISPR screens with a single-cell transcriptomics readout enables large-scale mapping of gene regulatory networks across multiple model species. In conclusion, by overcoming significant technical challenges associated with implementing transcriptome-wide single-cell omics methods in bacteria, we show that these approaches allow scalable interrogation of diverse phenotypic states and responses, such as virus-bacteria interactions and the outcomes of genetic perturbations.

Title: Mapping Decidual Immunity: Integrating Single-Cell and Spatial Multiomics in Human and Non-Human Primate Pregnancy

Abstract:

The maternal–fetal interface is a specialized immunological niche in which finely tuned interactions between maternal and fetal cells underpin successful pregnancy. Disruption of this balance can precipitate adverse outcomes, highlighting the need to define the cellular and molecular programs that govern local immunity. Here, we integrate multiomic and spatial approaches—including single-cell RNA sequencing (scRNA-seq), CITE-seq, V(D)J profiling, and Parse Biosciences’ Evercode™ platform—to map the transcriptional, functional, and spatial landscapes of decidual immune populations in humans and a non-human primate (NHP) pregnancy model.
In human term decidua, combined scRNA-seq and CITE-seq analyses of T cells uncovered clonal expansions of tissue-resident memory T cells marked by elevated ITGAE (CD103), PDCD1 (PD-1), and metabolic regulators such as SLC16A1. Clonotype mapping demonstrated compartmentalized distributions consistent with localized antigen exposure. Parallel profiling of decidual mucosal-associated invariant T (MAIT) cells revealed a decidua-specific transcriptional program characterized by upregulated tissue-repair genes (ANXA1, HMGB1), type-1 cytokines (IFNG, TNF), and homing receptors (ITGA4, CCR5). CITE-seq confirmed high surface expression of CD69 and CD49a, indicative of a pro-inflammatory yet regulatory, tissue-resident phenotype poised for immune surveillance and tissue remodeling.
Extending these findings to the rhesus macaque, spatial transcriptomic analysis of a sterile placental injury model revealed robust pro-inflammatory niches at sites of tissue damage. High-input single-cell profiling with Parse Evercode™ further demonstrated that sterile inflammation in utero imprints immune programs in fetal tissues, suggesting mechanisms by which the maternal environment shapes fetal immune development.
Together, this comprehensive atlas of decidual immunity—spanning T cell clonotypes, MAIT cell programming, and spatially resolved inflammatory responses—illuminates the cellular circuits that maintain pregnancy homeostasis. By applying single-cell, proteogenomic, and spatial modalities across human and NHP tissues, we uncover conserved pathways of immune regulation at the maternal–fetal interface and identify candidate targets for therapeutic modulation in pregnancy complications.
