Lectin pathway Lectin pathway The lectin pathway is a type of cascade reaction in the complement system, similar in structure to the classical complement pathway, in that, after activation, it proceeds through the action of C4 and C2 to produce activated complement proteins further down the cascade. In contrast to the classical complement pathway, the lectin pathway does not recognize an antibody bound to its target. The lectin pathway starts with mannose-binding lectin (MBL) or ficolin binding to certain sugars. In this pathway, mannose-binding lectin binds to mannose, glucose, or other sugars with 3- and 4-OH groups placed in the equatorial plane,
Extracellular matrix exist in varying degrees of stiffness and elasticity, from soft brain tissues to hard bone tissues. The elasticity of the ECM can differ by several orders of magnitude. This property is primarily dependent on collagen and elastin concentration, and it has recently been shown to play an influential role in regulating numerous cell functions. Cells can sense the mechanical properties of their environment by applying forces and measuring the resulting backlash. This plays an important role because it helps regulate many important cellular processes including cellular contraction, cell migration, cell proliferation, differentiation and cell death (apoptosis).
