Topics in This Issue: Cancer Testes Antigens,Immune Checkpoints,Inflammation Associated with Ischemia-Reperfusion and Integrin Targeting

This issue of the International Reviews of Immunology is dedicated to several topics: cancer immunotherapy, and basic and translational aspects of immunity. Two reviews, one focused on breast and the other on lung cancer, highlight the need to redefine the cancer testes antigens (CTAs) as novel information regarding their expression profile and biological role emerges. Two other reviews showcase pivotal molecules that keep in check immunity at two different levels: the transcription factor autoimmune regulator (AIRE) important to negative selection of the T-cell repertoire, and CD22 that limits the antigen-initiated B-cell response. Two other articles focus on the debated role of Toll-like receptors (TLRs) and inflammation in general, in ischemia-reperfusion lesions that follow cardiovascular disorders and stroke. Last but not the least, this issue hosts a review that discusses the role and translational potential of the α4 integrin for the treatment of inflammatory bowel disease (IBD).
