Myeloid Populations in Systemic Autoimmune Diseases
AbstractSystemic autoimmune diseases (SADs) encompass a wide spectrum of clinical signs as a reflection of their complex physiopathology. A variety of mechanisms related with the innate immune system are in the origin of the loss of self-tolerance in these diseases, and for most of them, the myeloid leukocytes are key actors. Monocytes, macrophages, dendritic cells, and neutrophils are first-line immune effectors located in the interface between innate and adaptive immunity. They are crucial in the organization of the local and systemic responses to damage-associated molecular patterns (DAMPs) and determine the intensity, orientation, and duration of the local immune response through the expression of chemokines, costimulatory or protolerogenic factors. In this review, we summarize the current knowledge about the role of the main myeloid populations in the induction and maintenance of systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), primary antiphospholipid antibody syndrome (PAPS), systemic sclerosis (SSc), and Sj ögren’s syndrome (SjS), based on the data from both mouse preclinical models and patients. According to these data, our challenge in the next few years is to better dissect the fine mechanisms underlying the pathological role of myeloid cells in these diseases in order to define specific cell sub sets or proteins that can be potential targets for drug development.

Boosting the sensitivity of in vitroβ-lactam allergy diagnostic tests. Chem Commun (Camb). 2020 Oct 14;56(80):11973-11976 Authors: Peña-Mendizabal E, Morais S, Maquieira Á Abstract The synthesis of structurally new haptens and the development of suitable antigens are essential for boosting the sensitivity of drug allergy diagnostic testing. Unprecedented structural antigens for benzylpenicillin and amoxicillin are characterised and evaluated in a cohort of 70 subjects with a turnkey solution based on consumer electronics.

BEST supplements to relieve joint pain: Is your arthritis playing up? The wetter and colder months could partially be to blame. These two pills may help.
CONCLUSIONS: Young adult IS patients in Korea exhibit low awareness and poor management of their risk factors. Although the short-term outcome was relatively favorable in those patients, having SLE was associated with unfavorable outcomes. More attention needs to be paid for improving awareness and controlling risk factors in this population. PMID: 33029967 [PubMed]

CONCLUSIONS: As the present study was the first investigation on the coagulation status in patients with AA, elevated D-dimer levels in alopecia areata may suggest a deficient coagulation in these patients that may contribute to an increase in the risk of thrombosis. Further studies are needed to evaluate this hypothesis using a larger sample size. PMID: 33034439 [PubMed - as supplied by publisher]
