linkurl:1. New clue to self-tolerance;http://f1000.com/5685958?key=sswwkkrpjfr7hxf Researchers identify a new population of regulatory T cells, important players in immunological self-tolerance, which can be induced by cytokine interleukin IL-35. These iTr35 cells, which can themselves make IL-35 and initiate the production of more iTr35 cells, can suppress and regulate immune responses in a variety of pathogenic models in mice, opening up a new direction in immunology research and presenting possible therapeutic implications.L. W. Collison, et al., "IL-35-mediated induction of a potent regulatory T cell population," linkurl:Nat Immunol,;http://www.ncbi.nlm.nih.gov/sites/entrez/20953201?dopt=Abstract&holding=f1000%2Cf1000m 2010.

linkurl:2. Another route to helper T;http://f1000.com/5750956?key=fd6jvlszdhbxkcj T helper 17 cells, which are crucial for host defense and autoimmunity, can differentiate in the absence of TGF-β signaling, contrary to conventional wisdom on Th17 differentiation. Th17 cells derived without TGF-β, however, are more pathogenic, suggesting the differentiation pathways may lead to different Th17 cell types.K. Ghoreschi, et al., "Generation of pathogenic T(H)17 cells in the absence of TGF-beta signalling," linkurl:Nature,;http://www.ncbi.nlm.nih.gov/sites/entrez/20962846?dopt=Abstract&holding=f1000%2Cf1000m 467:967-71, 2010.

Natural killer cells adapt, too;http://f1000.com/5808956?key=5qhq80hx23pyxfp In addition to their known role in the innate immune system, hepatic natural killer (NK) cells can also generate antigen-specific responses with memory that persists in the absence of the pathogens. These cells appear to act independently of T and B lymphocytes, the classical mediators of adaptive immunity, raising the interesting possibility of using NKs in vaccine development. S. Paust, et al., "Critical role for the chemokine receptor CXCR6 in NK cell-mediated antigen-specific memory of haptens and viruses," linkurl:Nat Immunol,;http://www.ncbi.nlm.nih.gov/sites/entrez/20972432?dopt=Abstract&holding=f1000%2Cf1000m 2010.

Key differentiation factor elucidated;http://f1000.com/4942963?key=rqw76cqskm8xcqr Researchers reveal details of how the aryl hydrocarbon receptor (AhR) regulates the differentiation of human regulatory T cells, and point to AhR as a potential target for mediating these cell types in autoimmune diseases. R. Gandhi, et al., "Activation of the aryl hydrocarbon receptor induces human type 1 regulatory T cell-like and Foxp3(+) regulatory T cells," linkurl:Nat Immunol,;http://www.ncbi.nlm.nih.gov/sites/entrez/20676092?dopt=Abstract&holding=f1000%2Cf1000m 11(9):846-53, 2010.

Avoiding self destruction;http://f1000.com/5389963?key=1lxmypmj55y3xm9 A new study provides clues to how a subset of CD8+ T cells helps the immune system avoid attacking self tissues and organs during vigorous immune responses to pathogens -- they suppress the immune response via their interactions with follicular T-helper cells. H.J. Kim, et al., "Inhibition of follicular T-helper cells by CD8(+) regulatory T cells is essential for self tolerance," linkurl:Nature,;http://www.ncbi.nlm.nih.gov/sites/entrez/20844537?dopt=Abstract&holding=f1000%2Cf1000m 467(7313):328-32, 2010.

Lu, et al., "Function of miR-146a in controlling Treg cell-mediated regulation of Th1 responses," linkurl:Cell,;http://www.ncbi.nlm.nih.gov/sites/entrez/20850013?dopt=Abstract&holding=f1000%2Cf1000m 142(6):914-29, 2010.

Complement-mediated asthma;http://f1000.com/5622958?key=1ywg798380515b2 Interleukin 17A has previously been associated with severe asthma, but its exact role was unknown. In this paper, researchers detail the pathway by which IL-17A mediates severe airway hyperresponsiveness (AHR) in mice, and document a novel mechanism involving IL-23 and elements of the complement system of the immune response.S. Lajoie, et al., "Complement-mediated regulation of the IL-17A axis is a central genetic determinant of the severity of experimental allergic asthma," linkurl:Nat Immunol,;http://www.ncbi.nlm.nih.gov/sites/entrez/20802484?dopt=Abstract&holding=f1000%2Cf1000m 11(10):928-35, 2010.
