2,4,5 Transmission of multi-drug-resistant strains of HIV is rare. (managedhealthcareexecutive.com)

During the second step in the HIV life cycle, the HIV envelope fuses with the CD4 cell membrane, allowing the viral genetic material to enter the host cell. (uspharmacist.com)
That is accompanied by condensation of two helical areas within gp41, leading to formation of the six helix package, facilitating close get in touch with from the viral and sponsor membranes and accompanied by fusion from the viral envelope using the cell membrane. (bioinbrief.com)

The strategy is targeted primarly to improve the pharmacokinetic properties from the fusion peptide by covalent linkage for an antibody. (bioinbrief.com)

The greatest risk factor for vertical transmission is thought to be advanced maternal disease, likely due to a high maternal HIV viral load. (medscape.com)
