Brain cancer treatment, where glioblastoma represents up to 50% of all CNS malignancies, is one of the most challenging calls for neurooncologists. The major driver of this study was a search for new approaches for the treatment of glioblastoma. We t…
Vitamin D deficiency, characterized by low circulating levels of calcifediol (25-hydroxyvitamin D, 25D) has been linked to increased risk of infections of bacterial and viral origin. Innate immune cells produce hormonal calcitriol (1,25-dihydroxyvita…
Human LL-37is an antimicrobial peptide forming thermostable supramolecular fibrils that surround bacterial cells. The crystal structure of LL-37bearing an I24C substitution of most buried position in the fibril revealed disulfide-bonded dimers that f…
Membrane disrupting antimicrobial peptides (AMPs) are often amphipathic peptides that interact directly with lipid bilayers. AMPs are generally thought to interact mostly with lipid head groups, but it is less clear how the lipid alkyl chain length a…
Heterologous synthesis of proteins or peptides in plant-based systems, referred to as plant molecular farming, is a practical and safe approach for the large-scale and cost-effective production of therapeutic biomolecules. In this context, monocotyle…
Neutrophil extracellular traps (NETs) have been described as a potential trigger of severe COVID-19. NETs are known as extracellular DNA fibers released by neutrophils in response to infection. If the host is unable to balance efficient clearance of…
Covid-19 has to date infected a confirmed 275 million people with 5.4 million, now dead, with the count rising every day. Although the virus, SARS-CoV2, causing Covid-19 infects many cells in the body, its infection of the upper and lower respiratory…
INTRODUCTION: Due to the increase of antibiotic resistant bacterial strains, there is an urgent need for development of alternatives to antibiotics. Cathelicidins can be such an alternative to antibiotics having both a direct antimicrobial capacity a…
Innate immune defense against deep tissue infection byis orchestrated by fibroblasts that become antimicrobial when triggered to differentiate into adipocytes. However, the role of this process in noninfectious human diseases is unknown. To investiga…
Recombinant analogs of a number of natural host-defense mammalian cathelicidins were obtained and predominant mechanism of their antibacterial action was studied. The ability of cathelicidins to suppress the growth of Pseudomonas aeruginosa producing…
Antimicrobial peptides (AMPs) are promising pharmaceutical candidates for the prevention and treatment of infections caused by multidrug-resistantpathogens, which are responsible for the majority of hospital-acquired infections. Clinical translation…
BACKGROUND AND OBJECTIVES: DNA-based therapeutic vaccines have been proposed as a promising strategy for the treatment of established HIV infections. However, these vaccines are often associated with certain shortcomings, such as poor immunogenicity…
PURPOSE: Corneal infection in humans caused bycan lead to blindness and the host ocular immune response to it is less studied. Herein, we investigate the expression of mediators of innate and adaptive immune responses in a rabbit model. METHODS: zoos…
Surgical site infections represent a significant clinical problem. Herein, we report a nanofiber dressing for topical codelivery of immunomodulating compounds including 1α,25-dihydroxyvitamin D(1,25(OH)D) and VID400, ainhibitor in a sustained manner,…
Copy number polymorphisms (CNPs) of antimicrobial peptides (AMPs) in livestock can influence the innate immune response of individuals. We conducted a high-resolution analysis of the genomic variations of porcine cathelicidin PR39 using cloned PR39 a…
Cathelicidins have antimicrobial and immunomodulatory activities. Previous studies have shown that chicken cathelicidin-2 (CATH-2) exerts strong anti-inflammatory activity through LPS neutralization. However, it is still unclear whether other intrace…
BACKGROUND: Older adults are more susceptible to respiratory tract infection than healthy working age adults. The increased susceptibility of older adults is thought to be interlinked with vitamin D status, nourishment, and immunological state in gen…
α-Synuclein (a-syn) oligomers and fibrils are behind neurodegeneration in Parkinson's disease (PD), but therapeutically targeting them is challenging. Amphipathic and cationic helical peptides inhibit amyloid formation and suppress neurotoxicity by s…
