Abstract:
Anergy is a state of long-term hyporesponsiveness in T cells that is characterized by an active repression of TCR signaling and IL-2 expression [1]. Several forms of anergy have been described and the past few years have brought to light an increasing number of 'anergic factors' involved in the induction and the active maintenance of the state in lymphocytes. The role of mTOR and other related metabolic sensors and regulators has recently emerged as of particular importance in broadening our view of anergy-inducing signals. We will discuss the role of these molecules in regulating the choice between anergy and activation, a decision faced by all T cells undergoing TCR stimulation. We will then explore the relationship between the induction of anergy and the induction of regulatory T cells as well as the potential crosstalk responsible for the phenomenon of infectious tolerance.

Special Features of Adaptive Immunity
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

B Cell Activation and Differentiation
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

Immune Response Against Viral Pathogens
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
