hematopoietic stem cells.
VetBooks.ir CD119 The IFN-γ receptor is found on B cells, macrophages and

monocytes, fibroblasts, and endothelial cells.

CD120 There are two TNF receptors (TNFR-I [CD120a], and TNFR-
II [CD120b]). TNFR-I is found at higher levels on epithelial cells,

whereas TNFR-II is more highly expressed on myeloid cells.

CD121 These are the two IL-1 receptors, IL-1RI and IL-1RII,
expressed on thymocytes, fibroblasts, keratinocytes, endothelial
cells (type I), and macrophages and B cells (type II).

CD122 The IL-2 receptor β chain expressed on T cells, activated B

cells, NK cells, and monocytes.

CD123 The IL-3 receptor α chain.

CD124 The IL-4 receptor expressed on T and B cells, fibroblasts,
endothelial cells, and stem cells.

CD125 The IL-5 receptor α chain.

CD126 The α chain of the IL-6 receptor expressed on B cells, plasma

cells, epithelial cells, and hepatocytes.

CD127 The IL-7 receptor expressed on stem cells, T cells, and
monocytes.

CD128 The IL-8 receptors expressed on leukocytes and
keratinocytes. Also called CXCR1 and -2.

CD130 The β chain of the IL-6 (with CD126) and IL-11 receptors is
found mainly on B cells but expressed at lower levels on most
leukocytes, epithelial cells, hepatocytes, and fibroblasts.

CD131 The common β chain of the IL-3 (with CD123), IL-5 (with
CD125), and GM-CSF (with CD123) receptors.

CD132 The common γ chain of IL-2 (with CD25 and CD122), IL-4
