Data suggest that up-regulation of S100A8 and S100A9 is a key component of early endometrial response to uterine involution in the post-partum period and to prevent chronic endometritis/uterine inflammation; up-regulation can be influenced by diet.
Study verified porcine calprotectin (S100A8/A9) expression at the protein level in multiple Haemophilus parasuis infected tissues and explored their molecular characterization.
Co-cultivation of pancreatic islets with unstimulated peritoneal macrophages in the presence of palmitate (to induce lipotoxicity) and high glucose (to induce glucotoxicity) synergistically increased the expression and release of islet-produced S100A8 in a Toll-like receptor 4 (TLR4)-independent manner.
Specific NLRC4 activation in Mrp8 (+) cells (primarily neutrophil lineage) is sufficient to cause severe inflammatory disease.
We present the reconstitution, purification, and characterization of mCP as well as the cysteine-null variant mCP-Ser. Apo mCP is a mS100A8/mS100A9 heterodimer, and Ca(II) binding causes two heterodimers to self-associate and form a heterotetramer
Chronic Pseudomonas aeruginosa biofilm infection reduces murine S100A8/ S100A9 expression and delays species-specific burn wound closure.
data suggest that S100A8/A9 acts directly on BV-2 microglial cells via binding to TLR4 and RAGE on the membrane and then stimulates the secretion of proinflammatory cytokines through ERK and JNK-mediated NF-kappaB activity in BV-2 microglial cells.
The results obtained in the present study demonstrate for the first time that S100A8 as well as MyD88 and NF-B are activated by T3 and that these molecules are directly involved in the thyroid hormone-induced cardiac hypertrophic response. These data suggest that one of the mechanisms underlying T3-dependent cardiac hypertrophy/failure may involve the activation of an inflammatory pathway.

Perinatal alarmins S100A8 and S100A9 specifically altered MyD88-dependent proinflammatory gene programs. S100 programming prevented hyperinflammatory responses without impairing pathogen defense. TRIF-adaptor-dependent regulatory genes remained unaffected by perinatal S100 programming and responded strongly to lipopolysaccharide, but were barely expressed.

S100A8 is primarily produced from CXCR2-expressing CD11b(+)Gr-1(high) cells, and it upregulates TNF-alpha production in CD11b(+)F4/80(+) cells through cellular cross-talk, which is an important mechanism in the development of Nonalcoholic fatty liver disease

This study identified Mrp8/14 and TLR4 as important modulators of the leukocyte recruitment cascade during inflammation via integrin beta2.
The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in the inhibition of casein kinase and as a cytokine. Altered expression of this protein is associated with the disease cystic fibrosis.
