The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
In diabetes, multipotent stromal cells (MSCs) are functionally deficient. It is unknown, however, whether their antibacterial function is compromised. In this study, MSCs were isolated from the bone marrow samples provided by nine diabetic and six no…
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…
Carica papaya is a perennial plant containing bioactive constituents with free radical-scavenging and immune-modulating activities. In contrast, the immune suppression is predominant in the periparturient period, where oxidative stress has a substant…
Antimicrobial peptides have a great potential to replace antibiotics in the treatment of bacterial infections. In order to improve the its stability, the antimicrobial peptides were incorporated in poly(L-lactic acid-co-D,L-mandelic acid) (LA-co-MA)…
Antimicrobial peptides (AMPs) are a diverse family of peptides that defend the mucosal surfaces of the oral cavity and other locations. Many AMPs have multiple functions and properties that influence aspects of innate defense and colonization by micr…
Human rhinoviruses commonly cause upper respiratory infections, which may be complicated by secondary bacterial infection. Vitamin D replacement reduces risk of acute respiratory infections in vitamin D-deficient individuals, but the mechanisms by wh…
BACKGROUND: The aim of this study was to assess the prognostic value of vitamin D, vitamin D binding protein (VDBP) and vitamin D-related peptides in septic shock patients in relation to hospital mortality. METHODS: This is a single-center, prospecti…
Bacterial infections are mostly due to bacteria in their biofilm-mode of growth, while penetrability of antimicrobials into infectious biofilms and increasing antibiotic resistance hamper infection treatment. In-vitro, monolaurin lipid nanocapsules (…
Influenza A virus is a leading cause of mortality in humans and poses a global health emergency due to its newly adapted and resistant strains. Thus, there is an urgency to develop novel anti-influenza drugs. Peptides are a type of biological molecul…
In this study, the use of cubosomes for topical delivery of the antimicrobial peptide (AMP) LL-37 was investigated. Topical delivery of AMPs is of great interest for treatment of skin infections caused by bacteria, such as Staphylococcus aureus. AMP…
The relatively low long-term survival rate of lung transplant recipients as compared to other organ recipients serves as an impetus to identify potential lung dysfunction as early as possible. There is an association between donor heavy alcohol use a…
Cathelicidins are effector molecules of vertebrate immunity that play vital roles against microbial invasion. They are widely identified in mammals, but few have been reported in Crocodilians, which are considered to be species with a powerful immune…
LL-37, the only known human cathelicidin which is encoded by the human antimicrobial peptide (CAMP) gene, plays a critical role in protection against bacterial infection. We previously demonstrated that cathelicidin is induced by 1,25-dihydroxyvitami…
OBJECTIVE: The aim of this study was to investigate the proteome of the gingival crevicular fluid comparing the relative abundance of proteins from type 2 diabetes mellitus (2DM) individuals and chronic periodontitis (CP) affected sites, subjects aff…
Pancreatic cancer remains one of the deadliest human cancers despite current advances in conventional therapeutics including surgery and adjuvant therapies. Here, we showed that LZ1, a peptide derived from a snake venom cathelicidin, significantly in…
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…
AIM: Vitamin D stimulates production of the endogenous antimicrobial peptides cathelicidin and β-defensin-2, which are expressed in the urinary tract. We investigated vitamin D status and levels of cathelicidin and β-defensin-2 and their association…
BACKGROUND: A better understanding of bronchiolitis heterogeneity might help clarify its relationship with the development of recurrent wheezing and asthma. OBJECTIVES: We sought to identify severe bronchiolitis profiles using a clustering approach a…
Preterm birth, defined as delivery before 37 weeks of gestation, is the leading cause of neonatal mortality and morbidity. Infection and inflammation are frequent antecedents of spontaneous preterm birth. Cathelicidin, an antimicrobial host defence p…
The innate immune element, cathelicidin antimicrobial peptide (CAMP), is vital in the formation of the antimicrobial barrier in skin. CAMP production is increased during epidermal differentiation and enriched in the stratum corneum. We recently ident…
