Answer- Memory b cells
The HIV causes particularly the destruction CD4+ T-helper cells but in addition to that it also affects the other half of the adaptive immune sytem that is B cells.Most importantly, the memory B cells are found to be damaged in the HIV infection.The memory B cells are required for the production of immune response to the infection which occurs again.The abundant macrophages in the HIV infection are present on the mucosal surface which is infected by the HIV virus produces cytokines but HIV virus don't kill the macrophages.The neutrophils are present slightly low in number incase of HIV infected individuals compare to the uninfected individual.

True or false: One molecule of IgG can bind to 2 differently structured antigens at the same time. True O False Question 5 3 pts A person with HIV has far fewer Helper T cells than a healthy person because the virus infects and destroys Helper T cells. Which other cell type will be less common in a person infected with HIV compared to an uninfected individual? Unactivated (immature) B cells Macrophages Memory B cells Neutrophils

QUESTION 1 3 po HIV predominantly infects T-helper cells, cells that are responsible for coordinating B- and T-cell activity. Based on this information, explain why HIV-infected individuals are at a very high risk for developing microbial infections. List the causative agent (virus) and discuss its properties. Name and briefly discuss 3 diseases that AIDS patients are more likely to contract.

As a Result of HIV-Induced Cytokine Imbalances that favor the Cytokine Production of TH2 Helper T Cells and discourage the Cytokine Production of TH1 Inflammatory T Cells, the Cytokine Response of an Individual infected with HIV will be skewed towards the Production of greater Amounts of -- A. Type 1 Cytokines, elevating Antibody-Mediated Responses. B. Type 2 Cytokines, elevating Antibody-Mediated Responses. C. Type 1 Cytokines, elevating Cell-Mediated Responses. D. Type 2 Cytokines, elevating Cell-Mediated Responses.

A) HIV functions by infecting healthy CD4+T cells, a type of white blood cell, that are necessary to fight infection. As the virus embeds in a T cell and the immune system produces more of these cells to fight the infection, the virus propagates in an opportunistic manner. Normally, T cells are produced at a rate s and die at a rate d. The virus, when present in the bloodstream as free virus, infect health T cells at a rate...

29. While HIV does not directly cause cancer, there is an increased risk for the development of various cancers when an HIV-infected individual develops AIDS. Which of the following constitutes an AIDS-defining cancer in an HIV positive person? (A) Pneumocystis pneumonia (B) Cervical cancer (C) Kaposi's sarcoma (D) Breast cancer 30. HIV specifically attacks and kills helper T cells. This drastically weakens the immune system because helper T cells (A) produce antibodies (B) turn off the immune response...

3. Macrophage has recently been diagnosed with HIV. To top it off after a stressful spring semester, Macrophage has now been infected with the CoVID-19 virus. IF Macrophage was healthy, what two main cells would be activated in response to cells infected with the COVID-19 virus (be specific)(2 pts) How would the cell responsible for eliminating CoVID-19 infected cells become activated (think 3 steps) (3 pts). What is the job of these two cells after activation has taken place (1...
