LL-37 protects rats against lethal sepsis caused by gram-negative bacteria.

We investigated the efficacy of LL-37, the C-terminal part of the only cathelicidin in humans identified to date (termed human cationic antimicrobial protein), in three experimental rat models of gram-negative sepsis. Adult male Wistar rats (i) were given an intraperitoneal injection of 1 mg Escherichia coli 0111:B4 LPS, (ii) were given 2 x 10(10) CFU of Escherichia coli ATCC 25922, or (iii) ha...

Modulation of the TLR-mediated inflammatory response by the endogenous human host defense peptide LL-37.

The sole human cathelicidin peptide, LL-37, has been demonstrated to protect animals against endotoxemia/sepsis. Low, physiological concentrations of LL-37 (< or =1 microg/ml) were able to modulate inflammatory responses by inhibiting the release of the proinflammatory cytokine TNF-alpha in LPS-stimulated human monocytic cells. Microarray studies established a temporal transcriptional profile a...

Propylene-Glycol Aggravates LPS-Induced Sepsis through Production of TNF-α and IL-6

Background : Propylene glycol (1,2-propanediol, PG) is a commonly used solvent for oral, intravenous, as well as topical pharmaceutical preparations. While PG is generally considered to be safe, it has been known that large intravenous doses given over a short period of time can be toxic. Objective: To evaluate the effect of PG in sepsis induced by the bacterial endotoxin lipopolysaccharide (LP...

Immunomodulatory Role of Clarithromycin in Acinetobacter baumannii Infection via Formation of Neutrophil Extracellular Traps.

Macrolide antibiotics have been shown to act as immunomodulatory molecules in various immune cells. However, their effect on neutrophils has not been extensively investigated. In this study, we investigated the role of macrolide antibiotics in the generation of neutrophil extracellular traps (NETs). By assessing ex vivo and in vivo NET formation, we demonstrated that clarithromycin is able to i...

Intracellular receptor for human host defense peptide LL-37 in monocytes.

The human cationic host defense peptide LL-37 has a broad range of immunomodulatory, anti-infective functions. A synthetic innate defense regulator peptide, innate defense regulator 1 (IDR-1), based conceptually on LL-37, was recently shown to selectively modulate innate immunity to protect against a wide range of bacterial infections. Using advanced proteomic techniques, ELISA, and Western blo...
