BACKGROUND Measurement of (1-->3)-beta-D-Glucan (BG) has emerged as an adjunct diagnostic strategy for invasive fungal infections (IFI). METHODS Subjects at 6 clinical sites in the United States…
Saccharomyces cerevisiae‐ and Candida albicans‐Derived Mannan Induced Production of Tumor Necrosis Factor Alpha by Human Monocytes in a CD14‐ and Toll‐Like Receptor 4‐Dependent Manner
Findings suggested that the mannan‐LBP complex is recognized by CD14 on monocytes and that signaling through TLR4 leads to the production of proinflammatory cytokines in a manner similar to that induced by LPS.
Cathelicidin Family of Antibacterial Peptides CAP18 and CAP11 Inhibit the Expression of TNF-α by Blocking the Binding of LPS to CD14+ Cells1
Cathelicidin peptides human CAP18 and guinea pig CAP11 probably exert protective actions against endotoxin shock by blocking the binding of LPS to CD14+ cells, thereby suppressing the production of cytokines by these cells via their potent binding activities for LPS and CD14.
Augmentation of the Lipopolysaccharide-Neutralizing Activities of Human Cathelicidin CAP18/LL-37-Derived Antimicrobial Peptides by Replacement with Hydrophobic and Cationic Amino Acid Residues
18-mer LLKKK is the most potent of the peptide derivatives, with therapeutic potential for gram-negative bacterial endotoxin shock, and the LPS-neutralizing activities of the amphipathic human CAP18/LL-37-derived 18-mer peptide can be augmented by modifying its hydrophobicity and cationicity.
An Antimicrobial Cathelicidin Peptide, Human CAP18/LL-37, Suppresses Neutrophil Apoptosis via the Activation of Formyl-Peptide Receptor-Like 1 and P2X71
Observations indicate that LL-37 cannot only kill bacteria, but also modulate (suppress) neutrophil apoptosis via the activation of FPRL1 and P2X7 in bacterial infections.

Solid data support the idea that the MT3 melatonin binding site is an enzyme, quinone reductase 2 (QR2), rather than a membrane melatonin receptor, and hypothesize that melatonin is a co‐substrate of QR2.
DDX1 is required for testicular tumorigenesis, partially through the transcriptional activation of 12p stem cell genes
It is concluded that DDX1 is a critical factor for testicular tumorigenesis, as in situ hybridization revealed thatDDX1 mRNA was produced in both seminoma and nonseminoma types of human TGCT samples.
A new chromogenic endotoxin-specific assay using recombined limulus coagulation enzymes and its clinical applications.
Characterization of β-Glucan Recognition Site on C-Type Lectin, Dectin 1
The results suggest that the amino acid sequence W221-I222-H223 is critical for formation of a β-glucan binding site in the CRD of dectin 1.
Antimicrobial Cathelicidin Peptide LL-37 Inhibits the LPS/ATP-Induced Pyroptosis of Macrophages by Dual Mechanism
LL-37 potently inhibits the LPS/ATP-induced pyroptosis by both neutralizing the action of LPS and inhibiting the response of P2X7 to ATP, which may provide a novel insight into the modulation of sepsis utilizing LL-37 with a dual action on the L PS binding and P2 X7 activation.
