The lentivirus human immunodeficiency virus (HIV) causes AIDS by interacting with a large
number of different cells in the body and escaping the host immune response against it. HIV …

Regulation, recognition and cell signaling involve the coordinated actions of many players.
To achieve this coordination, each participant must have a valid identification (ID) that is …

Vaccination against human immunodeficiency virus type 1 (HIV-1) requires an immunogen
which will elicit a protective immunity against viruses that show a high degree of genetic …
