ProNGF mediates death of Natural Killer cells through activation of the p75NTR-sortilin complex
چکیده انگلیسی
The common neurotrophin receptor P75NTR, its co-receptor sortilin and ligand proNGF, have not previously been investigated in Natural Killer (NK) cell function. We found freshly isolated NK cells express sortilin but not significant amounts of P75NTR unless exposed to interleukin-12 (IL-12), or cultured in serum free conditions, suggesting this receptor is sequestered. A second messenger associated with p75NTR, neurotrophin-receptor-interacting-MAGE-homologue (NRAGE) was identified in NK cells. Cleavage resistant proNGF123 killed NK cells in the presence of IL-12 after 20 h and without IL-12 in serum free conditions at 48 h. This was reduced by blocking sortilin with neurotensin. We conclude that proNGF induced apoptosis of NK cells may have important implications for limiting the innate immune response.
