Autophagy and Crohn's disease: at the crossroads of infection, inflammation, immunity, and cancer.
Inflammatory bowel diseases (IBD) are common inflammatory disorders of the gastrointestinal tract that include ulcerative colitis (UC) and Crohn's disease (CD). The incidences of IBD are high in North America and Europe, affecting as many as one in 500 people. These diseases are associated with high morbidity and mortality. Colorectal cancer risk is also increased in IBD, correlating with infla...
متن کاملAt the Crossroads of Inflammation and Cancer
Chronic inflammation and cancer are closely associated in the intestine. Anti-inflammatory medication reduces intestinal neoplasia, while colorectal cancer incidence is increased in ulcerative colitis. Cyclooxygenases are key to both diseases, yet the molecular basis of the association remains incompletely understood. Two recent Cell (Greten et al., 2004; Rakoff-Nahoum et al., 2004) papers illu...
متن کاملAutophagy: Cancer, Other Pathologies, Inflammation, Immunity, Infection, and Aging
Autophagy plays a direct or indirect role in health and disease. A simplified definition of autophagy is that it is an exceedingly complex process which degrades modified, superfluous (surplus) or damaged cellular macromolecules and whole organelles using hydrolytic enzymes in the lysosomes. It consists of sequential steps of induction of autophagy, formation of autophagosome precursor, formati...
متن کاملp62 at the Crossroads of Autophagy, Apoptosis, and Cancer
The signaling adaptor p62 is a multidomain protein implicated in the activation of the transcription factor NF-kappaB. Recent findings link p62 activity to the extrinsic apoptosis pathway, and Mathew et al. (2009) now show that the modulation of p62 by autophagy is a key factor in tumorigenesis. These findings place p62 at critical decision points that control cell death and survival.
متن کاملCD98 at the crossroads of adaptive immunity and cancer.
Adaptive immunity, a vertebrate specialization, adds memory and exquisite specificity to the basic innate immune responses present in invertebrates while conserving metabolic resources. In adaptive immunity, antigenic challenge requires extremely rapid proliferation of rare antigen-specific lymphocytes to produce large, clonally expanded effector populations that neutralize pathogens. Rapid pro...
