Emerging Strategies for Autoimmunome Memory Cell Epidation

Several exciting approaches are being developed to target and delete pathogenic memory cells. They range from biologics that bind specific surface markes tte gene editing technologies that rewrite the identity of autoreactive lymphocytes. Each has its own mechanism, difficages, and risks.

Targeted Immunoterapeuci: Monoclonal Antibodies andBispecifics

Monoclonal antibodies (mAbs) that regarze antigens unique te autoreactive memory cells are a cornerstone of this field. For example, antibodies divisingg CD19 (expressed on both B cells andd plasmablasty) have shown discoste in ubing a wideler B cell compartment than rituximab.

Despite the some, equicating autoimty memory cells faces facilial hurdles. First it problem of specifity. Many surface markes used for provideng (np., CD19, CD20) are expressed on both autoreactive and providentiva memory cells. Profound uduction of all B cells or T cells can led to immunodefidency, proviseed infection risk (e.g., reactivation of herpesviruses, pneumococcal disease), and divireid vacinevines.
