That HIV shield covering the virus includes a protein called gp120
, which in turn is covered by a layer of sugar.
The protein fragment of the vaccine candidate comes from gp120
, a protein that covers HIV like a protective envelope.
In this trial (HVTN 114), these "late boosts" consist of the GeoVax MVA62B vaccine with or without a gp120
The improved vaccine consists of a canarypox-based vaccine called ALVAC-HIV and a bivalent gp120
protein subunit vaccine with MF59, a different adjuvant from that used in the Thai trial, in an effort to achieve a more robust immune response.

Disruption of the blood-brain barrier function as a fundamental mechanism facilitating the entrance of HIV in the CNS followed by a conjunction of direct and indirect viral factors, such as viral proteins gp120
, tat and vpR has been observed.
Several HIV-1 proteins have been shown to be involved in ROS production and responsible to enhance the oxidative stress during disease progression, these include Nef (9, 10), Tat (11), gp120
(12) and Vpr (13).
Phylogenetic analyses of the C2-V3 region of the HIV-1 gp120
gene, and related protease and reverse transcriptase genes demonstrated clustering of HIV viral strains among the outbreak cases and similarity between strains identified in the outbreak and other strains in Southeast Asia.
Translation of env gene produces glycoprotein 160 (Gp160) that further is processed to give Gp120
There is cross-reaction between HIV gp120
and thrombocyte gp3a and between HIV p24 antibodies and platelets.
The results show that, despite general similarities in regions of the HIV-1 gp120
polypeptide that contact CD4, VRC01, VRC03 and b12, there are important differences in quaternary structures of the complexes these ligands form on native trimeric Env, and potentially explain differences in the neutralizing breadth and potency of antibodies with similar specificities.
La infeccion se inicia con la interaccion de la molecula gp120
del virus con el receptor CD4 expresado principalmente en los linfocitos T (LT), lo cual promueve la interaccion del virus con los correceptores virales CCR5 o CXCR4.
