Linking Retroelements to Autoimmunity
In this issue, Stetson et al. (2008) report a mechanism by which host cells avert an autoimmune response to self-nucleic acids. They show that the nuclease Trex1 prevents the accumulation of DNA derived from endogenous retroelements that, if left unchecked, trigger elevated production of type I interferons leading to autoimmunity.
متن کاملBasophils and IgE: Linking the Allergic Environment to Autoimmunity
As outlined in some of the accompanying articles in this issue, the role of the basophil as an effector cell in allergy and in host defense (particularly to parasites) has long been recognized. However, recent advances advocate for the basophil as an immunomodulatory cell that can promote naïve CD4 + T cell commitment to Th2 cell differentiation. While this is in keeping with the concept that t...
متن کاملLinking autoimmunity to the origin of the adaptive immune system
In jawed vertebrates, the adaptive immune system (AIS) cooperates with the innate immune system (IIS) to protect hosts from infections. Although targeting non-self-components, the AIS also generates self-reactive antibodies which, when inadequately counter-selected, can give rise to autoimmune diseases (ADs). ADs are on the rise in western countries. Why haven't ADs been eliminated during the e...
متن کاملAssociation of Melasma with Thyroid Autoimmunity: A Case-Control Study
Introduction: Melasma is a common acquired hypermelanosis seen mainly in women which occurs on the sun-exposed skin of the face. The exact cause of melasma is unknown. The majority of the cases are attributed to pregnancy, combined oral contraceptive pills, genetic factors, sun exposure, use of cosmetic products, thyroid disorders and anti-convulsant drugs. This study was performed to evaluate ...
متن کاملCommensals: Underappreciated Reservoir of Antibiotic Resistance
A ntibiotic resistance, reported for sulfonamides in the mid-1930s and for penicillins in the 1940s, remains a stubborn quandary. What was once confined mainly to hospitals increasingly involves multidrug resistance that encompasses communities and encircles the globe. Virtually all types of bacterial infections are becoming resistant to antibiotic treatments, according to officials at the Cent...
