Recent reports focusing on virulence factors of periodontal pathogens implicated proteinases as major determinants of remarkable pathogenicity of these species, with special emphasis on their capacity to modulate complement activity. In particular, bacteria-mediated cleavage of C5 and subsequent release of...

In innate immune cells, pathogens and danger signals activate TLRs, unleashing potent and tailored inflammatory responses. Previously, we reported that an immune-specific transmembrane adaptor, SLP adaptor and CSK interacting membrane protein (SCIMP), interacts with TLR4 via direct binding to its...

Complement plays an important role in the immune attack against invading microorganisms. However, blood-contacting medical device biomaterials lacking specific complement inhibitors, with free hydroxyl and/or amino groups, or with absorbed antibodies, may inappropriately activate complement. Inappropriate activation by either the...

β-Glucans are naturally occurring polysaccharides that are produced by bacteria, fungi and yeast. They are considered immunostimulants in fish acting on non-specific defense mechanism. Yeast-derived glucans from cell wall (Sterigmatomyces halophilus, β-Gluc/Sh) have been used for this purpose in this...

Statins exert pleiotropic and beneficial anti-inflammatory and antioxidant effects. We have previously reported that macrophages treated with statins increased the expression of heme oxygenase-1 (HO-1), an inducible anti-inflammatory and cytoprotective stress protein, responsible for the degradation of heme. In the...
