Immunostimulatory properties of the major protein from the stem of the Ayurvedic medicinal herb, guduchi (Tinospora cordifolia).

Ethnopharmacological Relevance: Guduchi (Tinospora cordifolia), a widely used plant in folk and Ayurvedic systems of medicine is well known for its immunomodulatory activity; however, the presence of an immunomodulatory protein (ImP) in guduchi has not been investigated.

Materials And Methods: Guduchi ImP was purified from dry stem powder extract by anion-exchange chromatography on Q-Sepharose. Characterization of guduchi ImP was performed by SDS-PAGE, periodic acid-Schiff staining, HPLC, and immunochemical analyses.

Dietary garlic (Allium sativum) lectins, ASA I and ASA II, are highly stable and immunogenic.

The immunomodulatory proteins present in garlic have recently been shown to be identical to the garlic lectins ASA I and ASA II [Clement F, Pramod SN, Venkatesh YP. Int. Immunopharmacol.

Identity of the immunomodulatory proteins from garlic (Allium sativum) with the major garlic lectins or agglutinins.

Garlic (Allium sativum), an important medicinal spice, displays a plethora of biological effects including immunomodulation. Although some immunomodulatory proteins from garlic have been described, their identities are still unknown. The present study was envisaged to isolate immunomodulatory proteins from raw garlic, and examine their effects on certain cells of the immune system (lymphocytes, mast cells, and basophils) in relation to mitogenicity and hypersensitivity.
