ancient-glutathione The year 2021 marked a significant point in the ongoing research and understanding of LL37, a fascinating human antimicrobial peptide. Also known as human cathelicidin LL-37, this peptide, composed of 37 amino acid residues, has garnered considerable attention for its diverse biological activities, ranging from potent antimicrobial functions to crucial roles in immune modulation and wound healing. Emerging research continues to unravel its complexities, revealing its involvement in various physiological and pathological conditions.Increased LL37 in psoriasis and other inflammatory disorders ...

LL-37, a key component of the innate immune system, is produced by white blood cells (mainly neutrophils) and is inducible by vitamin D作者：S Miura·2023·被引用次数：29—LL37is produced by skin injury and bacterial infectionand plays an important role in the early stages of psoriasis.. Its primary function is to combat a broad spectrum of pathogens, including bacteria, fungi, and viruses. Studies have shown that LL-37 has moderate antimicrobial activities against numerous Gram-negative and Gram-positive bacteria, including pathogens from the *Pseudomonas* and *Escherichia* genera. Furthermore, research has demonstrated that LL-37 has a strong antibacterial effect on *S作者：EL Acen·2021·被引用次数：31—The human cathelicidinLL-37has both antimicrobial and immunomodulatory properties and is dependent on vitamin D status.

This potent antimicrobial capacity makes LL-37 a promising candidate in the fight against antibiotic-resistant pathogens, a significant global health concern. The potential of human peptide LL-37 as an antimicrobial and anti-biofilm agent is also a subject of intense investigation. Beyond its direct antimicrobial effects, LL37 also has potent antimicrobial activity against Gram-positive and Gram-negative bacteria in the presence of 10% human serum.

However, the role of LL37 extends far beyond simple pathogen elimination. It possesses significant immunomodulatory properties, influencing both innate and adaptive immune responses.作者：M Mahlapuu·2021·被引用次数：43—This clinical trialHEAL LL-37was a phase IIb double-blind, randomized, placebo-controlled study, with the aim to evaluate the efficacy and ... For instance, LL-37 induced the same increase in IL-17A in mouse cells as the murine cathelicidin mCRAMP did, highlighting its capacity to shape inflammatory pathways. This peptide is produced by skin injury and bacterial infection and plays an important role in the early stages of psoriasis. Indeed, increased LL37 levels were also higher in the metastatic than in the non-metastatic group and controls, suggesting its involvement in cancer progression. Importantly, excessive production of LL37 in inflammatory skin disorders such as psoriasis may enhance LDL uptake and may increase the risk of cardiovascular disease. Furthermore, research indicates that LL37 can bind to various viral components, and LL-37 has been studied for its anti-HIV activity, suggesting a potential role in antiviral defenseNCT02225366 | Intratumoral Injections of LL37 for Melanoma.

The implications of LL37 in therapeutic applications are vast and continue to expandIn humans,cathelicidin LL-37is one of the main host defense peptides with a remarkable medical and biotechnological potential. Deregulation of .... Its role in wound healing is particularly noteworthy. LL-37 demonstrably berdampak pada beberapa mekanisme biologis yang relevan dalam penyembuhan luka. It attracts inflammatory cells, including monocytes and granulocytes, which are crucial for the initial stages of tissue repair. Clinical trials, such as the HEAL LL-37 study, a phase IIb double-blind, randomized, placebo-controlled trial, have aimed to evaluate the efficacy of LL-37 in healing difficult-to-heal venous leg ulcers. The efficacy of LL-37 cream in enhancing healing of diabetic foot ulcers has also been explored, showing promise in decreasing pro-inflammatory markers. HSEs expressing LL-37 through nonviral modification of skin cells are being investigated as a promising approach for preventing bacterial infections in skin equivalents.

Research into LL37 also extends to cancer therapy. A clinical research study NCT02225366 aimed to find the appropriate dose of LL37 that can be administered to patients with melanoma, suggesting its potential as an anti-cancer agent.作者：R Zhuxiao·2024·被引用次数：6—Stem cell therapy may prevent late-onset sepsis (LOS) viaantimicrobial peptide LL37 secretionand regulatory T cell (Treg) regulation. Identified as a core antibacterial and anticancer peptide, a 13-residue fragment of LL-37 has been developed based on total correlated spectroscopy.

The year 2021 saw continued exploration of LL37's structure and function. The human cathelicidin LL-37 is an amphipathic peptide, and understanding its various fragments and their specific activities, such as the solution structures of human LL-37 fragments, is crucial for therapeutic developmentRESEARCH ARTICLE The Effect of LL37 Antimicrobial ....
