how does it enter into a cell?
It enters by the adsorption of glycoproteins on its surface to receptors on the target cell followed by fusion of the viral envelope with the target cell membrane and the release of the HIV capsid into the cell.

what is rna interference? It is a biological process. what does it do? RNA molecules inhibit gene expression or translation, by neutralizing targeted mRNA molecules. what does rna stand for? Ribonucleic acid how has it evolved? UNANSWERABLE what relation does it have to medicine? It was observed that introducing sense and antisense RNA to par-1 mRNA in "Caenorhabditis elegans" caused degradation of the par-1 message. what relation does it have to cancer? It can provide a more specific approach to inhibit tumor growth by targeting cancer-related genes. how is this disease treated with rna? Chemotherapeutic agents and inhibit cell invasion and migration what are the variations among organisms? Its interference can be both systemic and heritable in plants and "C. elegans", although not in "Drosophila" or mammals. does rna cause viral infections? Yes, HIV, HPV, hepatitis A, hepatitis B etc how does it stimulate an immune response? It prevent the self-propagation of transposons and induces gene silencing in plants. what role does it play in insecticides? It is under development as an insecticide. what is the full form of the first viral infection that you mentioned? Human immunodeficiency viruses when was it discovered? 1981 by whom? U.S. Centers for Disease Control and Prevention what is its origins? The initial cases were a cluster of injection drug users and gay men with no known cause of impaired immunity who showed symptoms. how is it classified? It is a member of the genus "Lentivirus", part of the family "Retroviridae". how is it diagnosed? By using an enzyme-linked immunosorbent assay (ELISA) to detect antibodies to HIV-1. how is it treated? Using multiple antiretroviral drugs how is it transmitted? Although it is highly virulent, transmission does not occur through sex.

HIV [SEP] Entry to the cell
The HIV virion enters macrophages and CD4 T cells by the adsorption of glycoproteins on its surface to receptors on the target cell followed by fusion of the viral envelope with the target cell membrane and the release of the HIV capsid into the cell. Entry to the cell begins through interaction of the trimeric envelope complex (gp160 spike) on the HIV viral envelope and both CD4 and a chemokine co-receptor (generally either CCR5 or CXCR4, but others are known to interact) on the target cell surface. Gp120 binds to integrin αβ activating LFA-1, the central integrin involved in the establishment of virological synapses, which facilitate efficient cell-to-cell spreading of HIV-1.
