Major histocompatibility complex class II (MHCII) bound to a peptide antigen mediates interactions between CD4 T cells and antigen-presenting cells. Targeting peptide-MHCII with T cell antigen receptors (TCRs) and TCR-like antibodies has shown promise for autoimmune diseases and microbiome tolerance. To develop a general targeting approach, we introduce targeted recognition of antigen-MHC complex reporter for MHCII (TRACeR-II) for the rapid development of peptide-specific MHCII binders.

Article Synopsis
  • Integrin alpha V is crucial for cell adhesion and signaling during development, and mutations in its gene (ITGAV) can lead to serious health issues.
  • In three families, biallelic variants were found that caused either dysfunctional protein production or the integrin being misplaced, resulting in severe developmental problems like eye and brain abnormalities, inflammatory bowel disease, and immune issues.
  • Studies in patient cells and zebrafish models confirmed these mutations resulted in impaired immune signaling and developmental defects, linking the ITGAV variants to a newly identified human disease.

Malaria remains a global health problem, and the standard membrane feeding assay (SMFA) is a key functional assay for development of new interventions to stop malaria transmission from human to mosquito. For SMFA, media with ~ 10% of human serum has been used for infectious gametocyte cultures, however, there are multiple challenges to obtain a suitable human serum. Here we show a human-serum-free culture medium (HSF), which was a mixture of two stem cell culture media and AlbuMAX, supported infectious gametocyte growth.

Article Synopsis
  • Neisseria gonorrhoeae causes a common STI that can range from mild symptoms to severe complications like pelvic inflammatory disease and septic arthritis.
  • A young woman initially presented with fever and joint pain, leading to a diagnosis of inflammatory arthritis following immune suppressing treatments, which resulted in further neurological symptoms and muscle issues.
  • Testing revealed a positive urine gonorrhoeae PCR and septic arthritis; she was treated with antibiotics but showed only slow, incomplete recovery.

Exercise improves many comorbidities associated with epilepsy in addition to seizure control. Despite the ILAE consensus statement noting the positive effects of exercise in patients with epilepsy (PWE) and individual assessment of risks pertaining to these activities, many healthcare professionals, including neurologists, are unfamiliar with these guidelines. Neurostimulation is an increasingly prevalent treatment option for refractory epilepsy.
