 AB    In their earlier, much quoted, viewpoint article, Mario Clerici and Gene
       Shearer examined the role of T helper 1 (Th1)- and Th2-type responses in
       immune dysregulation associated with human immunodeficiency virus (HIV)
       infection. In this article, they consider the complications of a Th1-Th2
       model raised by the nomenclature, discuss the issue of cytokine
       production by non-T cells, and compare data obtained from T-cell clones
       with heterogeneous populations of leukocytes from patients. They define
       Th-cell responses and cytokine profiles as 'type 1' and 'type 2', and
       reemphasize the importance of strong cellular immune responses, along
       with the cytokines that augment and maintain such responses, in
       protective immunity against HIV infection and AIDS progression. Finally,
       they present a model of activation-induced, cytokine-modulated,
       programmed cell death as a major factor in the pathogenesis of HIV
       infection and AIDS.
