Phytohemagglutinin
Based on 7 publication(s) in Google Scholar
Phytohemagglutinin (PHA-M), the major seed lectin of the common bean, Phaseolus vulgaris, is a T-cell activator. Phytohemagglutinin stimulates human mononuclear leukocytes, inducing the expression of ChAT mRNA and potentiating ACh synthesis. Phytohemagglutinin induces dose- and time-dependent toxicity in THP-1 monocytes/macrophages, alters cellular morphology, causes organelle dysfunction, and increases the expression of NF-κB, COX2, IL-1β.

Description
IC50 & Target
Apoptosis[1]
In Vitro
Phytohemagglutinin (0.1-1000 µg/mL, 24 h) induces a reduction in cell number, the adoption of a rounded morphology, cytoskeletal destabilization and toxic response in THP-1 cells[1].
Phytohemagglutinin (0.1-1000 µg/mL, 24-72 h) reduces mitochondrial activity and lysosomal activity in MDM cells, causing significant viability loss at higher concentrations (1000 µg/mL) and prolonged exposure (72 h)[1].
Phytohemagglutinin (0.1-1000 µg/mL, 1-72 h) does not significantly induce ROS production in MDM cells at concentrations up to 1000 µg/mL over 72 h, showing only a slight increase in free radicals at 24 h with 1000 µg/mL[1].
Phytohemagglutinin (10-1000 µg/mL, 24 h) increases the expression of NF-κB, COX2, IL-1β and decreases the expression of TNF-α in MDM cells[1].
Phytohemagglutinin binds to the membranes of T-cells, stimulates metabolic activity, cell division [2].
Phytohemagglutinin (5µg/mL, 48 h) stimulates PBMCs to secrete high levels of inflammatory cytokines, including IL-6, TNF-α, IL-1β, IFN-γ, IL-4, IL-2, IL-12, IL-10, and IL-17, while significantly reducing IL-8 levels[4].
Phytohemagglutinin significantly reduces RGC-32 expression and inhibits the growth of renal cancer cells, an effect reversed by PD-L1 ligation[4].

Result:Induced a loss of membrane integrity, which in turn led to the detachment of THP-1cells from the culture flask at 1000 µg/mL.
Caused a reduction in cell number as a result of membrane destabilization.
Induced lysosomal membrane destabilization and reduction in MDM cell number at 100 and 1000 µg/mL.
Reduced mitochondrial membrane potential at 10 and 1000 µg/mL in MDM cells.
Elicited significant membrane permeabilization in MDM cells at 1000 µg/mL.
