Methods: We used immunohistochemistry (IHC), IgG4 repertoire profiling, and brain organoid experiments to explore this association.
Autoimmune disorders exhibit intricate pathology. Their mechanisms are complex, which attenuates the need for novel therapeutic interventions. Frexalimab, a potent monoclonal antibody targeting the dysregulated CD40-CD40L pathway, stands out as a formidable weapon against the assault of inflammation and tissue devastation.
