Problems solved by technology

However, the antibody cannot contact the virus remaining in the mononuclear macrophage, and the HIV envelope protein is prone to antigenic variation, and the original antibody loses its effect, so that the neutralizing antibody cannot play its due role
During the latent infection stage, the HIV provirus is integrated into the host cell genome, so HIV will not be recognized by the immune system, so it cannot be eliminated by autoimmunity alone
Another very important reason should be that, based on the mechanism of antibody killing and clearing antigens, it is speculated that after the immune antibody binds to the antigen, if it wants to produce an immune effect, it must either activate the complement and mediate the ADCC effect to dissolve the cellular antigen, but HIV It is not a cellular antigen; either it attracts phagocytes to phagocytize and clear the antigen through chemotaxis, but HIV is protected and proliferates in the phagocytes instead; or the antibody binds to the antigen to neutralize it, making it lose its infectivity, but HIV antigens have many structures Mutations, often making it difficult for antibodies to recognize
[0004] Judging from the current AIDS treatment methods that have been used clinically, the effect is not so ideal: (1) HIV reverse transcriptase inhibitors: can only prevent the infection of susceptible cells that have not been infected with HIV, and have no therapeutic effect on infected cells, and are toxic There are many side effects, including mi

Abstract

An AIDS blood plasma purifying therapeutic instrument in the medical science field comprises a blood separator, a blood plasma separator and a blood plasma purifier; the blood plasma separator can separate blood plasma from single blood corpuscles; the blood separator can filter multinuclear giant cells formed by lodging HIV; the blood plasma purifier can prepare and amplify infinite growing hybridomas macrophage strains with phagocytosis characteristic, the hybridomas macrophage strains are mixed in a cell frozen stock solution so as to enable cell concentration to reach 80%, and the purifier is made by pouring high-molecular material; the macrophage strains can swallow HIV; the purifier, the blood separator and the blood plasma separator can form a key external cycle system; when flood flows to pass the blood separator, the multinuclear giant cells containing HIV can be filtered; when the blood plasma separated by the blood plasma separator passes the purifier, containing HIV can be removed by a cleanser; the purified blood plasma can gather with single blood cells separated by the blood plasma separator, and can be returned, thus realizing purifying treatment purpose by removing HIV inside and outside blood cells.

Description

technical field [0001] The invention relates to the preparation and application of an AIDS plasma purification treatment instrument in the medical field, which is mainly used for removing HIV inside and outside blood cells of AIDS patients so as to achieve the purpose of treating AIDS. Background technique [0002] After HIV enters the human body, it is first swallowed by macrophages, but HIV quickly changes the acidic environment in certain parts of the macrophages and creates conditions suitable for its survival. Instead of being killed, HIV reproduces in them. Because CD4 is the receptor of HIV, the HIV that propagates in the macrophage passes through its envelope protein gp120 and with the help of gp41 (gp41 acts as a bridge, using its own hydrophobicity to mediate the fusion of the viral envelope and the cell membrane ) into CD4+ cells (cells, mononuclear macrophages, dendritic cells, etc.), proliferate rapidly in the cells, and produce 10 9 ~10 10 Virus particles, an...
