Learning Goal - Soluble Lectins

3 important questions on Learning Goal - Soluble Lectins

What are soluble lectins?

They are non-enzymatic non-antibody proteins that bind to sugars and exist in body fluids and act as pattern recognition receptors for PAMPs and DAMPs

Where are soluble lectins produced?

  1. Liver: C-reactive proteins, serum amyloid proteins
  2. Lungs: Pulmonary surfactant proteins
  3. Bone marrow and lymphoid tissues: Selectins
  4. Spleen, heart, skeletal muscle and brain: sites of synthesis for tetranectin
  5. GI tract and skin: throughout various locations

What is an example of a soluble lectin pathway?

Ficolin and Mannose Binding Lectin complexes (soluble lectins on the bacteria allow for effective binding and opsonization of the natural antibodies, leading to phagocytosis)
