The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
The skin is the largest and the most exposed organ in the body and its defense is regulated at several anatomical levels. Here, we explore how skin layers, including the epidermis, dermis, adipose tissue, and skin appendages, as well as cutaneous mic…
Clinical and epidemiological evidence supports that pregnancies carrying a male fetus are more vulnerable to infections and preterm birth, probably due to testosterone immunosuppressive properties. In human placentas, testosterone lowers the expressi…
Antibiotic resistance and biofilm formation are the main reasons for failure in treatment of bacterial infections. This study aimed to identify synergistic combinations of conventional antibiotics and novel synthetic antimicrobial and antibiofilm pep…
This study pertains to the new approach for the development of hybrid peptide LL-37Tα1 and its biomedical applications. A linear cationic hybrid peptide, LL-37Tα1 was derived from two parental peptides (LL-37 and Tα1) recognized as potent anti-endoto…
INTRODUCTION: Sepsis can result in acute lung injury. LL-37 is a small cationic host defense peptide involved in anti-inflammatory. In the current study, it was hypothesized that antimicrobial peptide LL-37 could play a protective role in attenuating…
BACKGROUND: Methicillin-resistant Staphylococcus aureus and multidrug-resistant Pseudomonas aeruginosa are becoming difficult to treat with antibiotics whereas Cationic Antimicrobial Peptides (CAMPs) represent promising alternatives. The effects of f…
The three-componentsystem senses and responds to cationic antimicrobial peptides (CAMPs), which induces the expression of theoperon and the genesand, modifying the surface net charge in, resulting in the repulsion of CAMPs. Thesystem has been only st…
OBJECTIVE: The human host defense peptide LL-37 both shows antimicrobial effects and modulates host cell properties. Here, we assess the effects of synthesized LL-37 on lipopolysaccharide (LPS)-induced inflammation in human periodontal ligament (PDL)…
Immunosenescence contributes to reduced vaccine response in elderly persons, and is worsened by deficiencies in nutrients such as Vitamin (Vit-D). The immune system is a well-known target of Vit-D, which can both potentiate the innate immune response…
Use of chlorhexidine in clinical settings has led to concerns that repeated exposure of bacteria to sub-lethal doses of chlorhexidine might result in chlorhexidine resistance and cross resistance with other cationic antimicrobials including colistin,…
The objective of the study was the investigation of the behaviour of cathelicidin-1 in the milk after experimental infection with two prominent bacterial pathogens (experiment 1:, experiment 2:and) as a potential early indicator for diagnosis of mast…
BACKGROUND: Tuberculosis is a leading cause of morbidity and mortality in humans worldwide. There is an urgent need for new and effective drugs to treat tuberculosis and shorten the duration of tuberculosis therapy. 1, 25-dihydroxy vitamin D3 (1,25 (…
Status of Fok I VDR polymorphism along with vitamin D, Vitamin D receptor (VDR), and cathelicidin levels in Tuberculosis (TB) patients compared to household contacts and implication of these findings in susceptibility to TB is not known. 150 active T…
Antimicrobial peptides (AMPs) are typically thought of as molecular hole punchers that directly kill pathogens by membrane permeation. However, recent work has shown that AMPs are pleiotropic, multifunctional molecules that can strongly modulate immu…
Skin bacterial colonization/infection is a frequent cause of morbidity in patients with chronic wounds and allergic/inflammatory skin diseases. This study aimed to develop a novel approach to eradicate meticillin-resistant Staphylococcus aureus (MRSA…
: To investigate the role of innate immunity in ocular rosacea.: Thirty-two patients with ocular rosacea patients (group-1) and 28 healthy volunteers (group-2) who served as controls were enrolled in the study. Tear function parameters were assessed,…
Inflammation is implicated in a wide range of disorders, and thought to be involved in most leading causes of death today in the United States with high associated costs. New insights into better understanding its etiology, detection and prevention a…
RNA aptamers are synthetic single stranded RNA oligonucleotides that function analogously to antibodies. Recently, they have shown promise for use in treating inflammatory skin disease as, unlike antibody-based biologics, they are able to enter the s…
OBJECTIVES: The lung-gut axis is known to be involved in the pathogenesis of Staphylococcus aureus pneumonia. However, the underlying mechanisms remain unclear. We examined the role of pulmonary mast cells (MCs) in the regulation of the lung-gut axis…
Bone and soft tissue infections are difficult problems in orthopedic surgery. Infections resulting in chronic osteomyelitis if established are difficult to eradicate. The delivery of local antibiotics for the treatment of open infected wounds of the…
