HIV infects which two types of cells?Multiple select question.Helper T lymphocytesMacrophagesB cellsSperm cellsNeutrophils

Answer to the Question

HIV primarily targets two specific types of cells in the immune system:

1. Helper T lymphocytes (CD4+ cells): These cells are crucial for the immune response, as they help activate other immune cells. HIV binds to the CD4 receptor on these cells, which allows the virus to enter and replicate within them.

2. Macrophages: These are another type of immune cell that engulfs and digests pathogens. HIV can also infect macrophages, which can lead to the virus being hidden in these cells, contributing to the persistence of the infection.

Other Cell Types Not Infected by HIV

• B cells: While they are a part of the immune response, B cells are not the primary targets for HIV.
• Sperm cells: HIV does not infect sperm cells.
• Neutrophils: Although they are involved in the immune response, neutrophils are not specifically targeted by HIV.

Final Summary

The two correct choices for the types of cells infected by HIV are Helper T lymphocytes and Macrophages.
