CD4 lymphocytes are T
lymphocytes that present in
plasma membrane receptor proteins
CD4.

CD4 lymphocytes are cells that HIV
infects within which the virus
. HIV has proteins in
capsule that bind to CD4 receptors
of lymphocytes. thatbond the
virus fuses the cell membrane and
content (RNA, reverse transcriptase,
, etc.) penetrates into the
and the viral replication
begins.

HIV RNA is converted into DNA by
reverse transcriptase. The new
is inserted into the material of
the lymphocyte the aid of enzymes
integrases. By transcription and
this DNA commands the
of proteins necessary for
assemblage of new viruses.
polypeptides are thus produced
then fragmented into proteins viral
enzymes by the protease. So
new HIV are assembled and
break cell membrane to gain
circulation.
