Itolizumab (Anti-Human CD6 Recombinant Antibody) is a humanized recombinant anti-CD6 monoclonal antibody (MAb) targeting the extracellular SRCR distal domain 1 of CD6. Itolizumab reduces T-cell proliferation and inhibits the production of pro-inflammatory cytokines, such as INF-γ, TNFα and IL-6. Itolizumab can be used in the research of psoriasis, rheumatoid arthritis (RA), COVID-19[1][2][3].
Itolizumab (100 μg/mL) inhibits T cell proliferation[4].
Itolizumab (0-100 μg/mL) inhibits Treg polarization and enhances acquisition of Th1 phenotype in PBMCs[4].
Itolizumab (40 μg/mL) reduces CD26hiCD161+ CD8+ T cells during culture of PBMCs overnight[5].
Itolizumab (40 μg/mL, 3-12 days) reduces the expression of IL-17 and IFN-γ in PBMCs stimulated in Th17 polarizing conditions[6].
Itolizumab (60 μg or 300μg, i.p., everyday) shows therapeutic efficiency in a humanized xenograft mouse model of Graft Vs Host Disease (GVHD)[7].
