PTPRC and ocular melanoma: After repeated administration of lipopolysaccharide (LPS) to bilateral nostrils, inflammatory cells such as macrophages (F4/80-positive), neutrophils (Ly-6G-positive), T cells (CD3e-positive) and B cells (CD45R-positive) locally infiltrated some regions of the olfactory mucosa (OM) in male and female mice, while these cells were not observed in the OM of saline-treated mice (Supplementary Figure S1).
