Is AIDS caused by insufficient immunological response to pathogens?

AIDS (Acquired Immunodeficiency Syndrome) is caused by the Human Immunodeficiency Virus (HIV), which specifically targets and destroys CD4+ T cells, crucial components of the immune system. This leads to a progressive deterioration of the immune response, making the body more susceptible to opportunistic infections and certain cancers. So, while insufficient immunological response is a consequence of HIV infection, AIDS itself is directly caused by the virus and its effects on the immune system.
