HIV infects FDC cells

HIV is a retrovirus. Retroviruses infect using LH/albumin binding receptors (my hypothesis). Could HIV infect using the Fc receptors?

albumin and the immune system

FDC have high levels of C3 complement receptors and they display the antigen carried by them or from antibodies taken in by Fc receptors.

Could FDC also be taking in albumin with antigens bound to them using the Fc receptor?

TNF alpha increased plasma albumin

peyer's patches removed caused higher albumin

the lymph fluid contains albumin as well...think of albumin as an protein sponge collecting things

How do follicular dendritic cells collect antigens for display? Can FDC collect antigens from albumin?
