HIV-1 most commonly uses the chemokine receptors CCR5 and/orCXCR4 as co-receptors to enter target immunological cells【1】.
甚至,缺了这俩,HIV依然可以感染(真是逆天了)
Even without the availability of either co-receptor (even CCR5), the virus can still invade cells if gp41 were to go through an alteration (including its cytoplasmic tail) that resulted in the independence of CD4 without the need of CCR5 and/or CXCR4 as a doorway【2】
