Exercise Mobilizes Early And Late Differentiated Cd8 T Cells Expressing A Marker Of Exhaustion, Rebekah Hunt, Mahmoud Elzayat, Emily C. Lavoy

International Journal of Exercise Science: Conference Proceedings

T cell differentiation occurs following activation of key functions, such as proliferation and cytokine production. Naïve (NA) and central memory (CM) T cells are early differentiated, whereas effector memory (EM) and RA+ effector memory cells (EMRA) are later differentiated. CD57 expression, a putative marker of exhaustion, has also been used to identify later differentiated cells, although recent data indicate CD57 can also be expressed by NA and CM. Exercise mobilizes EM and EMRA to a greater extent than NA and CM. Separately, exercise has been shown to preferentially mobilize CD57+ cells. Whether these exercise responsive CD57+ cells arise from highly …
