Lectins
From WikiLectures
Lectins are proteins or lipopolysaccharides of plant or bacterial origin that associate with membrane receptors.
- mitogenic lectins: stimulate mitoses,
- use of phytohemagglutinin (PHA) to stimulate mitosis of lymphocytes from peripheral blood (diagnostic purposes).
- non-mitogenic lectins: other manifestations of functional activity of sensitive cells.
- preventing sperm cells from entering the unfertilized egg (the egg behaves as if it has already been fertilized).
The transmission of stimuli from lectin-associated cellular receptors to the cytoplasm is explained by the activation of universal cellular mediators (cAMP, cGMP).
