context: HIV infection is a slowly progressing disease [1] caused by human immunodeficiency virus (HIV) [2] [3]. The virus infects cells of the immune system that have CD4 receptors on their surface: T-helpers, monocytes, macrophages, Langerhans cells [4], dendritic cells, microglia cells [5]. As a result, the immune system is depressed, the acquired immune deficiency syndrome (AIDS) develops, the patient's body loses its ability to defend itself against infections and tumors, and secondary opportunistic diseases arise that are not characteristic of people with normal immune status [6] [7] [8] [ 9] [10] [11].
