PPT-Chemokine Dependent Entry into the Thymus

T cell progenitors migrate from the bone marrow or fetal liver to the thymus based on chemokine receptor expression The expression of CCR7 CCR9 and CXCR4 are vital for T cell progenitor entry into the thymus as deficiencies in any of these receptors particularly CCR9 leads to a drastic reduction in . MCP1 released by adipocytes attracts CCR2expressing monocytes into the adipose tissue where they di57492erentiate into macrophages leading to lowgrade in57493ammation that contributes to insulin resistance 4 Mice de57481cient for CCR2 have reduced m Digital Laboratory.
