Dysregulated autoantibodies targeting AGTR1 are associated with the accumulation of COVID-19 symptoms.

Coronavirus disease 2019 (COVID-19) presents a wide spectrum of symptoms, the causes of which remain poorly understood. This study explored the associations between autoantibodies (AABs), particularly those targeting G protein-coupled receptors (GPCRs) and renin‒angiotensin system (RAS) molecules, and the clinical manifestations of COVID-19. Using a cross-sectional analysis of 244 individuals, we applied multivariate analysis of variance, principal component analysis, and multinomial regression to examine the relationships between AAB levels and key symptoms.

Could CGRP mAbs for migraine trigger rheumatoid arthritis? Insights from a case report.

Background: Case reports suggest that calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) may trigger inflammatory flares in patients with autoimmune diseases.

Case Description: A 56-year-old woman with a history of severe migraines, experienced improvement in migraine frequency and intensity after starting fremanezumab 225 mg monthly. However, three months into treatment, she developed symmetric inflammatory polyarthralgias.

Paracrine rescue of MYR1-deficient mutants reveals limitations of pooled CRISPR screens.

is an intracellular parasite that subverts host cell functions via secreted virulence factors. Up to 70% of parasite-controlled changes in the host transcriptome rely on the MYR1 protein, which is required for the translocation of secreted proteins into the host cell. Mice infected with MYR1 knock-out (KO) strains survive infection, supporting a paramount function of MYR1-dependent secreted proteins in virulence and proliferation.

Analysis of Complement Factor H gene polymorphisms and their association with clinical manifestations ofleptospirosis.

Leptospirosis is caused by pathogenic leptospires, posing a significant public health problem. Host susceptibility to Leptospira infection is a multifactorial trait, and the host's genetic background can influence both the establishment of infection and the severity of the disease. Complement Factor H (FH) plays a crucial role in the interaction between pathogenic bacteria and the host.
