T cells are critical for controlling S. aureus infection and gradually become hyporesponsive and anergic as the infection progresses towards persistence, potentially resulting in failure of the host immune response to promote sterilizing immunity.

Continuous depletion of CD4+ T helper cells, key players of the adaptive immune system, is a hallmark of chronic HIV-1 infection and progression to AIDS. Chronic hyperactivation of CD4+ T cells is thought to be key to their depletion. Here, the authors show that active HIV-1 replication induces in vivo bystander activation of CD4+ T cells, which are specific for persistent herpes virus antigens.

Haemophagocytic lymphohistiocytosis (HLH) is a potentially fatal inflammatory disease. The symptoms are the result of hypercytokinaemia and organ infiltration by lymphocytes and macrophages. In this paper, the authors show that in vivo IFNγ neutralization has a dramatic curative effect on clinical and biological manifestations of experimental HLH.

Mycobacterium tuberculosis is one of the best examples of successful co-evolution, since the bacilli have infected one third of the human population, but in 90% of the cases without causing overt disease. Despite this, increasing incidence of HIV infection and emergence of drug-resistant strains means that tuberculosis is in fact an extremely serious emerging threat to global health.
