Endogenous antimicrobial peptide LL-37 induces human vasodilatation [PDF]

open access: yesBritish Journal of Anaesthesia, 2008
Septic shock includes blood vessel dilatation and activation of innate immunity, which in turn causes release of antimicrobial peptides such as LL-37. It has been shown that LL-37 can attract leucocytes via the lipoxin A(4) receptor (ALX, FPRL1). ALX is also present in vascular endothelial cells. To explore possible ways of pharmacological intervention

The human cathelicidin peptide LL-37 inhibits pancreatic cancer growth by suppressing autophagy and reprogramming of the tumor immune microenvironment

open access: yesFrontiers in Pharmacology, 2022
Pancreatic cancer is amongst the most lethal malignancies, while its poor prognosis could be associated with promotion of autophagy and the tumor immune microenvironment.

Impact of LL-37 on anti-infective immunity [PDF]

open access: yesJournal 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,

CXCR2 specific endocytosis of immunomodulatory peptide LL-37 in human monocytes and formation of LL-37 positive large vesicles in differentiated monoosteophils

open access: yesBone 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 ...

Human defensins and LL-37 in mucosal immunity [PDF]

open access: yesJournal 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.

Cathelicidin LL-37 Ignites Primed NLRP3 Inflammasomes in Rosacea [PDF]

open access: yesJournal of Investigative Dermatology, 2021
Microbes and commensal mites contribute to the development of inflammation and neurovascular dysregulation in rosacea. Cathelicidin family proteins are epithelial antimicrobial peptides expressed in higher-order mammals. In humans, mature LL-37 is cleaved from its precursor in response to microbial infection, UV light, and injury.

SP-LL-37, human antimicrobial peptide, enhances disease resistance in transgenic rice. [PDF]

open access: yesPLoS ONE, 2017
Human LL-37 is a multifunctional antimicrobial peptide of cathelicidin family. It has been shown in recent studies that it can serve as a host's defense against influenza A virus.

Effects of LL-37 on Gingival Fibroblasts: A Role in Periodontal Tissue Remodeling? [PDF]

open access: yes, 2018
Mounting evidence suggests that the host defence peptide, LL-37, plays a role in both inflammation and in wound healing; however, the role of this peptide in the remodeling and maintenance of oral tissues is not yet fully understood.

The Role of Cathelicidin LL-37 in Cancer Development [PDF]

open access: yesArchivum 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.
