Unleash the power of mStab 1 for cancer immunotherapy

mStab1-1.26, InVivoPure+ is a mouse monoclonal antibody against mouse Stabilin-1, also known as Clever-1 or FEEL-1. Stabilin-1 is a scavenger receptor expressed by sinusoidal endothelial cells (ECs) in the liver, lymph nodes, spleen, and bone marrow.


It has also been shown that Stabilin-1 in type II macrophages and tumor vasculature acts as a new immunosuppressive molecule in cancer. Karikoski et al 2014 showed that Stabilin-1 supports the binding of tumor-infiltrating lymphocytes to tumor vasculature and increases the understanding of leukocyte immigration to tumors. The ability of anti-Stabilin-1 antibody treatment to attenuate tumor progression in WT mice in vivo is therapeutically relevant. Thus, Stabilin-1 may be an emerging new target for modulating immune evasion and lymphatic spread in cancer (Karikoski et al 2014).

Moreover, Dunkel et al 2018 reported that Stabilin-1 does not appear to influence antibody production by controlling B cell numbers and humoral immune responses in the spleen. Instead, the study suggests that Stabilin-1 in monocytes/macrophages controls the overall activity of B cells via the production of inflammatory cytokines.

Deletion or neutralization of Stabilin-1 enhances the antitumor immune response at least in melanoma, lymphoma and breast cancer (Karikoski et al 2014  and Riabov et al 2016). The efficacy of anti-Stabilin 1 antibodies in some experimental models has led to the development of fully human anti-Stabilin-1 antibodies that are currently being tested in clinical trials for cancer immunotherapy. Thus, the current observations suggest that interfering with Stabilin-1 function should not lead to suppression of antibody production, but may actually enhance the humoral immune response against tumor antigens (Dunkel et al 2018).
