Gene Ontology (GO) analysis was performed for all of the filtered LR pairs, and the enriched biological process terms are listed in ascending order of adjusted p values. To further investigate the cellcell communication that occurs specifically between tS2 and T cells, 15 LR pairs closely related to T cell action were chosen, and their spatial colocalization patterns were extracted with STopover. Then, extracted CCs for LR pairs were intersected with the colocalized domain between tS2 and NK/T cells, and the modified CCs were presumed to represent key locations for interaction between tS2 and NK/T cells.
