Phytolacca americana Lectin
Phytolacca americana Lectin (PWM) is an acidic monomeric glycoprotein specific to N-acetylglucosamine and a B cell-specific stimulator. Phytolacca americana Lectin acts as a mitogen to induce cell mitosis. Phytolacca americana Lectin sensitizes B cells to Toll-like receptor stimulation, enabling their activation by immunostimulatory DNA. When used in combination with copurified microbial Toll-like receptor ligands, Phytolacca americana Lectin triggers B cell proliferation and immunoglobulin secretion.

IL-8 |
Phytolacca americana Lectin induces mitosis in peripheral lymphocytes through cell surface binding[2].
Phytolacca americana Lectin (1-10 μg/mL) induces the proliferation of live-gated CD19+ peripheral blood B cells and promotes plasmablast differentiation, while B cell receptor cross-linking via anti-Ig interferes with these effector functions[3].
Phytolacca americana Lectin significantly induces the expression of intracellular TNF in monocytes, as detected by mean fluorescence intensity[3].
Phytolacca americana Lectin (10 μg/mL; 24 h) induces IL-8 secretion in HEK293 cells transfected with TLR2, and this activity is partially dependent on TLR2[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:human TLR2-transfected HEK293 cells
-
Concentration:10 μg/mL
-
Incubation Time:24 h
-
Result:Induced IL-8 secretion in TLR2-transfected HEK293 cells, with production almost doubled compared to non-transfected cells.
Reduced PWM-induced IL-8 production by approximately 50% (p=0.03) compared to isotype control after pre-treatment with 10 μg/mL anti-TLR2 mAb.
