The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
The system of antimicrobial peptides (AMP) is one of the most ancient mechanisms of the macroorganism resistance to infectious pathogens invasion. The aim of the study was to determine the role of the antimicrobial peptides system and periodontal pat…
Ureaplasma parvum is a commensal bacterium in the female reproductive tract but has been associated with pregnancy complications such as preterm prelabor rupture of membranes and preterm birth (PTB). However, the pathologic effects of U. parvum in th…
OBJECTIVES: This study aimed to evaluate the potential anti-inflammatory effects of vitamin D supplementation under uremic conditions, both in vivo and in vitro, and its effects on the parameters of mineral metabolism. METHODS: Thirty-two hemodialysi…
The efficiency of existing cell lysis methods to isolate nucleic acids from diverse bacteria varies depending on cell wall structures. This study tested a novel idea of using broad-spectrum antimicrobial peptides to improve the lytic efficiency of ha…
Preservation of intestinal stem cells (ISCs) plays a critical role in initiating epithelial regeneration after intestinal injury. Cathelicidin peptides have been shown to participate in regulating intestinal damage repair. However, it is not known ho…
To study the molecular interplay between TLRs and complement representing ancient danger-sensing mechanisms, we examined the regulation of the C3a/anaphylatoxin C3a receptor (C3aR) axis in normal human epidermal keratinocytes (NHEKs) by treatment wit…
Some antimicrobial peptides (AMPs), microRNAs (miRs), and Toll-like receptor 4 (TLR-4) are involved in autoimmune diseases, which may be affected by exercise training. The purpose of this study was to investigate the effect of an eight-week combined…
To explore whether glycosuria induces virulence of uropathogens, in turn facilitating urinary tract infection (UTI), we exposed group B Streptococcus (GBS) strain 10/84 to human urine plain or with 300 mg/dL glucose (mimicking moderate glycosuria). E…
Chemerin-derived peptide Val-Pro(p4) restricts the growth of a variety of skin-associated bacteria, including methicillin-resistant(MRSA). To better understand the antimicrobial potential of chemerin peptide, we compared p4 activity against MRSAto ca…
Antimicrobial peptides (AMPs) have gained interesting as a new type of antimicrobial agent. The cathelicidin-derived antimicrobial peptide PMAP-23 has broad-spectrum antibacterial activity, and to improve its antimicrobial activity, we used amino aci…
Host defense peptides (HDPs) are part of the innate immune system and constitute a first line of defense against invading pathogens. They possess antimicrobial activity against a broad spectrum of pathogens. However, pathogens have been known to adap…
Protozoan parasites, such as(), remained as a global health problem of the current century.is a major cause of cutaneous leishmaniasis (CL) in developed and developing countries. Traditionally, amphotericin B is prescribed as an alternative drug, whi…
Colorectal cancer (CRC) remains a leading cause of cancer mortality. Here, we define the colonic epithelial expression of cathelicidin (LL-37) in CRC. Cathelicidin exerts pleotropic effects including anti-microbial and immunoregulatory functions. Gen…
The advancement of deformity-specific implants and surgical techniques has improved the surgical treatment of Adult Spine Deformity (ASD), allowing surgeons to treat more complex deformities. Simultaneously, high rates of medical and surgical complic…
K9CATH is the sole cathelicidin in canines (dogs) and exhibits broad antimicrobial activity against both Gram-positive and Gram-negative bacteria. K9CATH also modulates inflammatory responses and binds to LPS. These activities depend on the secondary…
SARS-CoV-2 infection begins with the association of its spike 1 (S1) protein with host angiotensin-converting enzyme-2 (ACE2). Targeting the interaction between S1 and ACE2 is a practical strategy against SARS-CoV-2 infection. Herein, we show encoura…
This study aims to push the frontier of the engineering of human cathelicidin LL-37, a critical antimicrobial innate immune peptide that wards off invading pathogens. By sequential truncation of the smallest antibacterial peptide (KR12) of LL-37 and…
Group A Streptococcus (GAS) causes diverse human diseases, including life-threatening soft-tissue infections. It is accepted that the human antimicrobial peptide LL-37 protects the host by killing GAS. Here, we show that GAS extracellular protease Sc…
Viral infections, such as those caused by Herpes Simplex Virus-1 (HSV-1) and SARS-CoV-2, affect millions of people each year. However, there are few antiviral drugs that can effectively treat these infections. The standard approach in the development…
Antimicrobial peptides (AMPs) are one of the primary mechanisms used by the skin in the early stages of immune defense. AMPs have a broad antibacterial activity and also show antifungal and antiviral attributes. Various studies have also shown that l…
