IgG autoantibodies in bullous pemphigoid directly induce a pathogenic MyD88-dependent pro-inflammatory response in keratinocytes.

Unlabelled: While autoantibodies in bullous pemphigoid (BP) are known to activate the innate immune response, their direct effect on keratinocytes, and the contribution of BP-IgG autoantibody-dependent keratinocyte responses to BP pathology is largely unknown. Herein, we performed multiplex immunoassays and bulk RNA-seq on primary keratinocytes treated with IgG from BP patients or controls. We identified a pro-inflammatory and proteolytic response with release of several cytokines (IL-6, IL-24, TGF-β1), chemokines (CXCL16, CTACK, MIP-3β, RANTES), C1s, DPP4, and MMP-9.

An Overview of Adolescent Psychostimulant Use.

Adolescence marks a period of significant neural maturation and development of lifelong habits, including the potential use of recreational psychostimulant drugs. Increased prevalence of drug adulteration and fatalities related to drug overdose pose new challenges for individuals who use drugs recreationally. As the prevalence of recreational psychostimulant use drastically increases during young adulthood, pediatric and adolescent health care providers can play a crucial role in the lifelong well-being of their patients by identifying those with risk factors for consequences associated with substance use at an early age.

Readiness assessments for gender-affirming surgical treatments: A systematic scoping review of historical practices and changing ethical considerations.

Transgender and gender diverse (TGD) are terms that refer to individuals whose gender identity differs from sex assigned at birth. TGD individuals may choose any variety of modifications to their gender expression including, but not limited to changing their name, clothing, or hairstyle, starting hormones, or undergoing surgery. Starting in the 1950s, surgeons and endocrinologists began treating what was then known as transsexualism with cross sex hormones and a variety of surgical procedures collectively known as sex reassignment surgery (SRS).

Isolation and Genome Analysis of an Amoeba-Associated Bacterium Strain Ely Copper Mine From Acid Rock Drainage in Vermont, United States.

Protozoa play important roles in microbial communities, regulating populations predation and contributing to nutrient cycling. While amoebae have been identified in acid rock drainage (ARD) systems, our understanding of their symbioses in these extreme environments is limited. Here, we report the first isolation of the amoeba from an ARD environment as well as the genome sequence and annotation of an associated bacterium, strain Ely Copper Mine, from Ely Brook at the Ely Copper Mine Superfund site in Vershire, Vermont, United States.

Multiple Variants of SARS-CoV-2 in a University Outbreak After Spring Break - Chicago, Illinois, March-May 2021.

To prevent transmission of SARS-CoV-2, the virus that causes COVID-19, colleges and universities have implemented multiple strategies including testing, isolation, quarantine, contact tracing, masking, and vaccination. In April 2021, the Chicago Department of Public Health (CDPH) was notified of a large cluster of students with COVID-19 at an urban university after spring break. A total of 158 cases of COVID-19 were diagnosed among undergraduate students during March 15-May 3, 2021; the majority (114; 72.
