The only human cathelicidin antimicrobial peptide, playing key roles in innate immune defense, wound healing, and modulation of inflammatory responses.
Treatment of Chronic Obstructive Pulmonary Disease (COPD) is based on bronchodilation, with inhaled corticosteroids or azithromycin associated when frequent exacerbations occur. Despite the proven benefits of current treatment regimens, the need for…
Mesenchymal stem/stromal cells (MSCs) have demonstrated promise in pathogenic acute respiratory distress syndrome models and are advancing to clinical efficacy testing. Besides immunomodulatory effects, MSC derived conditioned medium (CM) has direct…
: Biomarkers for the diagnosis of heart failure (HF) are clinically essential. Circulating antimicrobial peptides LL-37 has emerged as a novel biomarker in cardiovascular disease, however, its relevance as a biomarker for acute HF are undetermined.:…
Outer-membrane vesicles (OMVs) produced bydeliver bacterial components to host cells, provide a mechanism for stabilization of secreted components and may allow the bacteria to exert 'long-range' effects in the gastric niche, promoting persistence. I…
Sepsis, which is characterized by multiple organ dysfunctions as a result of an unbalanced host-inflammatory response to pathogens, is potentially a life-threatening condition and a major cause of death in the intensive care units (ICUs). However, ef…
In this study, we demonstrated the development of colistin dependence in Acinetobacter baumannii isolates after exposure to the human cationic antimicrobial peptide LL-37. The LL-37-induced colistin-dependent mutants showed susceptibility to many oth…
Daptomycin-nonsusceptible (DAP-NS)often exhibits gain-in-function mutations in thegene (involved in positive surface charge maintenance). Standard β-lactams, although relatively inactive against methicillin-resistant(MRSA), may prevent the emergence…
Chronic rhinosinusitis (CRS) is a chronic infection of the nasal cavity and paranasal sinuses associated with the presence of a microbial biofilm. Extracellular DNA (eDNA) is an important component of the biofilm matrix. Antimicrobial peptides (AMPs)…
Atopic dermatitis (AD) is the most common chronic inflammatory skin disease in the world. AD is a complex pathology mainly characterized by an impaired skin barrier, immune response dysfunction, and unbalanced skin microbiota. Moreover, AD patients e…
In humans and other primates, 1,25(OH)vitamin Dregulates the expression of the cathelicidin antimicrobial peptide (CAMP) gene via toll-like receptor (TLR) signaling that activates the vitamin D pathway. Mice and other mammals lack the vitamin D respo…
The abuse of antibiotics and the consequent increase of drug-resistant bacteria constitute a serious threat to human health, and new antibiotics are urgently needed. Research shows that antimicrobial peptides produced by natural organisms are potenti…
BACKGROUND: Cathelicidins are a class of antimicrobial peptide, and the murine cathelicidin-related antimicrobial peptide (mCRAMP) has been demonstrated in vitro to impair Salmonella enterica serovar Typhimurium proliferation. However, the impact of…
Bacteriological, cytological and proteomics data have been obtained from ewes in two experiments, after intramammary challenge withor. Animals were sampled before and sequentially after challenge. Conventional techniques were employed for bacterial i…
OBJECTIVE: Antimicrobial peptides are widely present in nature, with many of the antimicrobial peptides having antimicrobial activity against Gram-positive and Gram-negative bacteria, fungi, parasites, and even coated viruses. Internal fixation of fr…
are protozoan parasites that predominantly reside in myeloid cells within their mammalian hosts. Monocytes and macrophages play a central role in the pathogenesis of all forms of leishmaniasis, including cutaneous and visceral leishmaniasis. The pres…
BACKGROUND: Rosacea is a common skin disease associated with increased expression of cathelicidin, kallikrein 5 (KLK5), toll-like receptor (TLR) 2, and abnormal barrier function. Recently, it was reported that hyaluronan (HA) could influence immune f…
Foodborne illness caused by consumption of food contaminated withis one of the most common causes of diarrheal disease and affects millions of people worldwide. The rising emergence and spread of antimicrobial resistance, especially in some serotypes…
Host defense peptides (HDPs) are crucial components of the body's first line of defense that protect organisms from infections and mediate immune responses. Defensins and cathelicidins are the two most important families of HDPs in mammals. In this r…
