LL-37 Cap-18 Peptide Vial

LL-37 Cap-18 is an antiseptic agent that can be used to treat fungal infections and serious bacterial infections. It has proved to be useful against skin infections, particularly in cases where the disease is resistant to most anti-fungal agents. In addition, it has also shown promise in fighting against bacterial skin infections due to fungal causes, such as candida albicans.

LL-37 (Cap-18) Peptide Vial 5mg

Scientific research have shown that LL-37 Cap-18 is an antibacterial protein that can be used to treat fungal infections and bacterial infections. It has proved to be useful against bacterial skin infections, particularly in cases where the disease is resistant to most anti-fungal agents. In addition, it has also shown promise in fighting against bacterial skin infections due to fungal causes, such as candida albicans. Recently, researchers have been studying the peptide LL-37’s benefits for cathelicidic dermatitis and how this substance can benefit people with this chronic skin disorder.

LL-37 can be used to treat cathelicidic dermatitis as this substance has proved effective in reducing the inflammation caused by this condition. This Peptide works by inhibiting the production of proinflammatory cytokines, which is one of the main causes of inflammation that can be attributed to cathelicidic dermatitis. As a result, it helps to eliminate the yeast and bacteria that cause cathelicidic skin disorder, thus relieving the symptoms associated with the condition.

LL-37 Research


As an immune system component, LL-37 is considered a antimicrobial peptide andoperates by adhering to and interfering with bacterial lipopolysaccharide (LPS), a critical component of gram-negative bacteria. Additionally, it inhibits the growth of gram-positive bacteria, making it effective against staph infections and other bacterial-related disorders [1].

According to studies on skin infections, normal skin has minimal levels of LL-37, but it rapidly accumulates when pathogens penetrate the body. Additionally, as seen in animal experiments, this peptide functions well with other proteins such as mice beta-defensin 2 to defeat the infection [2].

Tissue repair

LL-37 cap-18 peptide is antibacterial and controls the balance of pro- and anti-inflammatory chemicals in mice. However, scientists say it’s tough to balance inflammation and tissue recovery. Because while inflammatory reactions assist the body fight invaders, they can also obstruct healing, induce scar tissue formation, and even trigger autoimmune illnesses. Clinical studies have found that LL-37 therapy has the ability to balance inflammation, aid wound closure and healing by affecting macrophages, which plays an important role in the cause of inflammation when infections penetrate the body [3].

When macrophages recognize pathogens, they alert the rest of the body to defend. Next, the immune system destroys the infections, while macrophages produce new signals to lower inflammation. According to animal studies, LL-37 cathelicidin peptide reverses macrophage activation, turning anti-inflammatory macrophages pro-inflammatory.

LL-37 also inhibits biofilm formation, which can help heal wounds caused by P. aeruginosa and Staph infections. In addition, as shown in   animal studies, it can kill bacteria and promote wound healing by interacting with fibroblasts and keratinocytes [2].

Inflammatory Diseases

LL37 is primarily an antibacterial peptide, but it also helps inflammatory illnesses and autoimmune diseases like lupus, arthritis, and psoriasis. Ll-37 modulates the immune system by decreasing apoptotic keratinocytes, enhancing IL-18 and IFN-alpha generation, modifying neutrophils, and reducing atherosclerotic plaque levels.

The immune system isn’t always affected in the same manner by LL-37/CAP-18. In some circumstances, inactivated T-cells respond to the peptide by increasing their inflammatory activity, while activated T-cells decrease it.

Further research shows that LL 37 Cap-18 has homeostatic benefits, maintaining immune system regulation and reducing the danger of infection-induced over activity.

Experts believe LL-37 Cap-18 could help control autoimmune inflammation. New research shows it may be a therapy for autoimmune disease [4].


LL-37 cap-18 has been shown to help arthritis because of it’s ability to reduce inflammation. During experiments the synthetic peptide was administered into arthritic joints of rats with great success [5].

Another study on mice found that LL-37 Cap-18 protects against collagen damage caused by inflammatory arthritis [6]. Direct application of LL-37 to afflicted joints can reduce disease severity. Because LL 37 is abundant in inflamed tissues, scientists assume it has anti-arthritic properties. The peptide also appears to regulate interleukin-32, a molecule linked to arthritis.

There’s additional evidence that toll-like receptor 3 activation exacerbates arthritic symptoms. By binding to TLR4, it can produce anti-inflammatory actions [7].

Lung Disease

LPS has been detected in several species in clinical trials. When inhaled, this chemical stimulates healthy lung tissue. However, it does not treat respiratory diseases like asthma or COPD. The peptide LL-37 may help treat toxic dust syndrome [8].

According to research findings on LL-37 peptide and lung illness, the peptide enhances epithelial cell proliferation and tissue repair. In addition, drawing pulmonary epithelial cells to the injury site encourages the formation of blood vessels that nourish and maintain the new tissue [9].

Intestinal Cancer

Studies reveal that the LL-37 peptide may help with stomach and intestinal cancers by reducing intestinal inflammation. While the investigation is currently limited, vitamin D exposure has anti-cancer properties [10].


Due to its versatile and beneficial properties, LL-37 Cap 18 peptide holds promise for various therapeutic applications, including infectious diseases, wound healing treatments, and even potential applications in dermatology and cancer therapy. Ongoing research continues to explore its potential in these areas.
