Eotaxin2, also named myeloid progenitor inhibitory factor (MPIF2), is a member of the CC chemokine subfamily and is designated CCL24. Eotaxin2 is constitutively expressed in the jejunum and spleen. It can also be induced in the lung by allergen challenge and IL4. LPS and IL4 also differentially regulate the expression of Eotaxin2 in monocytes and macrophages. Mouse Eotaxin2 cDNA encodes a 119 amino acid (aa) precursor protein that shares approximately 58% aa sequence identity with human Eotaxin2. Functionally, Eotaxin2is most closely related to CCL11/Eotaxin and CCL26/Eotaxin3. The three proteins share low sequence homology but have been shown to be potent eosinophil chemoattractants that bind and activate the chemokine receptor CCR3, a receptor that is highly expressed in eosinophils. Eotaxin2 also has the ability to suppress myeloid cell proliferation, a biological function not shared by Eotaxin.

CCL25 (thymus expressed chemokine), also known as TECK (thymus-expressed chemokine), is a CC chemokine that is distantly related (twenty some % amino acid sequence identity) to other CC chemokines. Mouse CCL25 cDNA encodes a 144 amino acid residue precursor protein with a 23 amino acid residue signal peptide that is cleaved to yield a 121 residue mature protein. Mouse CCL25 shares 49% amino acid sequence identity with human CCL25. The expresssion of human and mouse CCL25 was shown to be highly restricted to the thymus and small intestine. Although dendritic cells have been demonstrated to be the source of CCL25 production in the thymus, dendritic cells derived from bone marrow do not express CCL25. The gene for mouse CCL25 has been mapped to chromosome 8.

CCL27, also known as CTACK (cutaneous T cel-lattracting chemokine), ALP, ILC, and ESkine, is a member of the CC family of chemokines. Mature mouse CCL27 is a 95 amino acid (aa) protein that shares 57% aa and 87% aa sequence identity with human and rat CCL27, respectively. It shares 18-31% aa sequence identity with other mouse CC chemokines. An alternately spliced form of mouse CCL27, known as PESKY, is localized to the nucleus and promotes cellular migration. CCL27 is constitutively expressed by keratinocytes and is upregulated by inflammatory stimuli and in wounded skin. CCL27 binds the chemokine receptor CCR10, glycosaminoglycans in the extracellular matrix, sulfated tyrosine residues on PSGL1, and determinants on the surface of fibroblasts and endothelial cells. CCL27 cooperates with CCL17/TARC in inducing the migration of cutaneous lymphocyte antigen (CLA) positive memory T cells to the skin during inflammation. Endothelial cellbound CCL27 can mediate the adhesion of those cells to CLA+ T cells. CCL27 also induces the migration of keratinocyte precursors from bone marrow to the skin, thereby promoting wound healing. In humans, serum CCL27 levels are elevated and correlate with disease severity in atopic dermatitis, psoriasis vulgaris, and mycosis fungoides.
