Human ficolin-2 is an important lectin complement pathway activator that is secreted from liver cells and has been implicated as an anti-infection innate immune molecule. However, the role of ficolin-2 protein and its dynamic changes over the course of and in the prognosis of chronic hepatitis B (CHB) and hepatocellular carcinoma (HCC) remain unclear. In(More)
Ficolins are serum complement lectins, with a structure similar to mannose-binding lectin (MBL) and lung surfactant protein (SP)-A and SP-D. Ficolins activate the lectin complement system and play important roles in host innate immunity. Ficolins are members of the collectin family of proteins, which act as pattern recognition receptors (PRRs). They are(More)
Ficolin-2 is an important serum complement lectin. Here, we describe novel findings indicating that serum ficolin-2 concentrations in multiple tumor patients are significantly lower than those in healthy donors. Administration of exogenous ficolin-2 or ficolin-A (a ficolin-2-like molecule in mouse), with only once, could remarkably inhibit the tumor cells(More)
Macrophages are the primary host target cells of Mycobacterium tuberculosis (M.tb). However, little is known about the changes of membrane glycopatterns of macrophages in response to M. tb infection. Using lectin microarrays we compared the differential expression of glycopatterns of macrophages upon stimulation with the heat-inactivated virulent M.tb H37Rv(More)
