Regulation of LL-37 in Bone and Periodontium Regeneration
Life, 2022 The goal of regenerative therapy is to restore the structure and function of the lost tissues in the fields of medicine and dentistry. However, there are some challenges in regeneration therapy such as the delivery of oxygen and nutrition, and the risk of infection in conditions such as periodontitis, osteomyelitis, etc. Leucine leucine-37 (LL-37) is a

The Role of Cathelicidin LL-37 in Cancer Development [PDF]
Archivum Immunologiae et Therapiae Experimentalis, 2015 LL-37 is a C-terminal peptide proteolytically released from 18 kDa human cathelicidin protein (hCAP18). Chronic infections, inflammation, tissue injury and tissue regeneration are all linked with neoplastic growth, and involve LL-37 antibacterial and immunomodulatory functions.

Human defensins and LL-37 in mucosal immunity [PDF]
Journal of Leukocyte Biology, 2009 Abstract Defensins and LL-37 play key roles in maintaining mucosal barriers against invasive infection and initiating immune responses after infection or injury to mucosal surfaces. Defensins are widespread in nature and have activity against a broad range of pathogens. Defensins have direct antimicrobial effects and

Cathelicidin LL-37 in Health and Diseases of the Oral Cavity
Biomedicines, 2022 The mechanisms for maintaining oral cavity homeostasis are subject to the constant influence of many environmental factors, including various chemicals and microorganisms. Most of them act directly on the oral mucosa, which is the mechanical and immune barrier of the oral cavity, and such interaction might lead to the development of various oral ...

The ratio of serum LL-37 levels to blood leucocyte count correlates with COVID-19 severity
Scientific Reports, 2022 Beneficial effects of vitamin D on COVID-19 progression have been discussed in several studies. Vitamin D stimulates the expression of the antimicrobial peptide LL-37, and evidence shows that LL-37 can antagonize SARS-CoV-2.

Impact of LL-37 on anti-infective immunity [PDF]
Journal of Leukocyte Biology, 2004 AbstractHost defense peptides (often called cationic antimicrobial peptides) have pleiotropic immunomodulatory functions. The human host defense peptide LL-37 is up-regulated at sites of infection and has little or no antimicrobial activity in tissue-culture media but under the same conditions, demonstrates immunomodulatory effects on epithelial cells,

Bone Reports, 2020 Immunomodulatory peptide cathelicidin/LL-37 induces human monocyte differentiation into a novel bone repair cell, the monoosteophil. We now demonstrate that LL-37 is endocytosed by monocytes over a period of 6 days producing large (10 × 2 μm ...

Carbamylated LL-37 as a modulator of the immune response [PDF]
Innate Immunity, 2016 Carbamylation of lysine residues and protein N-termini is an ubiquitous, non-enzymatic post-translational modification. Carbamylation at sites of inflammation is due to cyanate formation during the neutrophil oxidative burst and may target lysine residues within the antimicrobial peptide LL-37. The bactericidal and immunomodulatory
