Acute lung injury (ALI) and severe sepsis are common critical illnesses associated with the mobilization of bone marrow-derived cells into the circulation. By identifying and determining these cells' functional characteristics, unique prognostic biomarkers can be developed to help investigators understand the mechanisms underlying the pathophysiology of these disorders. We previously ... More

Elevated apolipoprotein E (apoE) synthesis within crushed sciatic nerves advocates that apoE could benefit axonal repair and reconstruction of axonal and myelin membranes. We created an apoE-mimetic peptide, COG112 (acetyl-RQIKIWFQNRRMKWKKCLRVRLASHLRKLRKRLL-amide), and found that postinjury treatment with COG112 significantly improved recovery of motor and sensory function following sciatic nerve crush in ...

MacMARCKS mutation blocks macrophage phagocytosis of zymosan.
Authors:Zhu Z, Bao Z, Li J
Journal:J Biol Chem
PubMed ID:7629059
'A major protein kinase C substrate, MacMARCKS (F52, MPR), was examined for its role in phagocytosis. In macrophage-phagocytosing zymosan particles, MacMARCKS was concentrated around nascent phagosomes as detected by immunofluorescent microscopy. The effector domain of MacMARCKS contains the phosphorylation sites, a calmodulin binding site, as well as a putative actin ... More
Identification and characterization of murine SCARA5, a novel class A scavenger receptor that is expressed by populations of epithelial cells.
Authors:Jiang Y, Oliver P, Davies KE, Platt N
Journal:J Biol Chem
PubMed ID:16407294
'Epithelia are positioned at a critical interface to prevent invasion by microorganisms from the environment. Pattern recognition receptors are important components of innate immunity because of their ability to interact with specific microbe-associated structures and initiate immune responses. Several distinct groups of receptors have been recognized. One of these, the ... More
