  Phytohaemagglutinin - WrongDiagnosis.com
Name of the Organism: Phytohaemagglutinin (Kidney Bean Lectin) This compound, a lectin or hemagglutinin, has been used by immunologists for years to trigger DNA synthesis in T lymphocytes, and more recently, to activate latent human immunodeficiency virus type 1 (HIV-1, AIDS virus) from human peripheral lymphocytes.
Besides inducing mitosis, lectins are known for their ability to agglutinate many mammalian red blood cell types, alter cell membrane transport systems, alter cell permeability to proteins, and generally interfere with cellular metabolism.
Associated Foods: Phytohaemagglutinin, the presumed toxic agent, is found in many species of beans, but it is in highest concentration in red kidney beans (Phaseolus vulgaris).

 Histol Histopathol, Vol 13, Pryme et al   (Site not responding. Last check: 2007-10-23)
The growth of a transplantable murine non-Hodgkin lymphoma tumour, developing either intra-peritoneally as an ascites tumour or subcutaneously as a solid tumour, has been shown to be markedly diminished by including phytohaemagglutinin (PHA), a lectin present in raw kidney bean (Phaseolus vulgaris) in the diet.
In NMRI mice fed PHA within the range 0.45-7.0 mg/g diet, tumours which developed during a 10 day period after subcutaneous injection of cells were about 35% of the dry weight of those in lactalbumin-fed (control) animals.
Experiments with a second murine tumour cell line (a plasmacytoma) in Balb/c mice gave similar results indicating that the effect of PHA was not restricted to a single tumour system.

 Phytohaemagglutinin
Structure and or Composition of Toxin: Phytohaemagglutinin, a kidney bean lectin, is the presumed toxic agent and is found in many species of beans.
Phytohaemagglutinins are composed of subunits with different binding sites.
Thus, the preventive measure of red kidney bean poisoning is to eat well cooked kidney beans.

Therefore, stimulation of peripheral lymphocytes of human immunodeficiency virus-1 infected patients in successive clinical stages was studied by phytohaemagglutinin and other stimulants.
Stimulation by phytohaemagglutinin decreased in patients with AIDS related complex to 63.1%, with AIDS to 13.6% of control values.
Radio-detoxified endotoxin alone or in combination with phytohaemagglutinin stimulated lymphocytes of both controls and patients with AIDS related complex slightly.

 Mechanism of Lymphocyte Transformation induced by Phytohaemagglutinin
The role of phytohaemagglutinin (PHA) determinants and lymphocyte surface reactive sites has been investigated in the lymphocyte transformation phenomenon.
Results suggest that the mitogenic moiety of the PHA molecule is closely related to or identical with the antigenic determinant sites, and that some of these PHA antigenic sites are similar to those found amongst the antigenic configuration on the surface of lymphocytes.

 Glia Literature - Myelin basic protein inhibits the calcium response to phytohaemagglutinin in human lymphocytes.   (Site not responding. Last check: 2007-10-23)
Pre-treatment of human lymphocytes with myelin basic protein results in a lower rising of cytosolic concentration of free calcium after stimulation with phytohaemagglutinin.
It is not due to a interaction between myelin basic protein and phytohaemagglutinin, but appears to be a consequence of the binding of the protein to the cell surface.
The reduction of the rise of cytosolic calcium induced by phytohaemagglutinin is specific for the myelin basic protein because other proteins like albumin and protamine have no effect.

Lymphocyte transformation responses to phytohaemagglutinin and pokeweed mitogen in patients at differing stages of HIV infection: are they worth measuring?
The influence of disease stage on T lymphocyte subsets and lymphocyte transformation responses (LyTR) to phytohaemagglutinin (PHA) and Pokeweed mitogen was assessed.
RESULTS--The median CD3 and CD4 counts and LyTR to PHA and Pokeweed mitogen were highest in patients with persistent generalised lymphadenopathy (PGL) and decreased progressively in the order: asymptomatic patients, those with ARC, those with AIDS.
