Figure 3. Schematic illustration of distribution of various resident immune cells in the ocular tissues.
(A) Resident immune cells are located in different parts of the ocular system. In the conjunctiva, cDCs, macrophages, B cell, and T cells are detected; in cornea, cDCs and macrophages comprise the main resident immune cells; in choroid, cDCs and macrophages and in retina microglia, perivascular macrophages, and cDCs are considered the main resident immune cells; in the lacrimal gland, cDCs, macrophages, and B cells are predominant resident immune cells. (B) To date, resident pDCs are reported in the central and peripheral cornea, limbus, bulbar conjunctiva, choroid, retina, and lacrimal gland
