Abstract 4879: Delineating lymphocyte aggregates from tertiary lymphoid structures using spatial transcriptomics

Abstract Tertiary Lymphoid Structures (TLSs) are ectopic lymphoid structures that form in chronically inflamed non-lymphoid tissue. The presence of TLSs in tumors is largely associated with favorable outcomes among patients and also exhibit positive associations with response to immune checkpoint blockade. Although mainly comprised of lymphocytes (B cells and T cells), they are considered a separate entity from lymphocyte aggregates within tissue. Lymphocyte aggregates are fairly routine to identify in H Part 1 (Regular Abstracts) ; 2024 Apr 5-10; San Diego, CA. Philadelphia (PA): AACR; Cancer Res 2024;84 (6Suppl): Abstract nr 4879.
