Modulation of host antimicrobial peptide (beta-defensins 1 and 2) expression during gastritis [PDF]

, 2002
Background: beta-Defensins are a newly identified family of antimicrobial peptides that are expressed by epithelia on mucosal surfaces where their production is augmented by infection or inflammation.

Estudo da estrutura e da solvatação do HNP-3, um antibiótico natural, por dinâmica molecular Study of the structure and solvation of the HNP-3, a natural antibiotic, by molecular dynamics

Química Nova, 2004
The structure and hydration of the HNP-3 have been derived from molecular dynamics data using root mean square deviation, radial and energy distributions. Three antiparallel beta sheets were found to be preserved.

The Network of Colonic Host Defense Peptides as an Innate Immune Defense Against Enteropathogenic Bacteria

Frontiers in Immunology, 2020
Host defense peptides, abundantly secreted by colonic epithelial cells and leukocytes, are proposed to be critical components of an innate immune response in the colon against enteropathogenic bacteria, including Shigella spp., Salmonella spp ...

Lactobacillus strains modulate TNF-α induced β-defensin-2 expression in IECs.

, 2020
Caco2 cells were pre-stimulated separately with Lactobacillus alone (A) and post-stimulation with TNF-α 12 h (B). The expression of β-defensin-2 expression was analyzed by RT-PCR. Caco2 cells with or without presence of TNF-α were used as controls.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...
