Cathelicidins are an ancient class of antimicrobial peptides (AMPs) with broad spectrum bactericidal activities. In this study, we investigated the diversity and biological activity of cathelicidins of buffalo, a species known for its disease resista…
Atherosclerosis is a chronic inflammatory disease of arterial wall. Mitochondrial DNA (mtDNA) and human antimicrobial peptide LL-37 (Cramp in mice) are involved in atherosclerosis. Recently, mtDNA has been found to escape from autophagy and cause inf…
Lactose handling by the human gut by most people, beyond being breast-fed, has been considered a disorder rather than physiological. A non-human mammalian milk source is novel for the majority. During the first 6 months of life, when neonates and inf…
BACKGROUND: The innate immune response to tuberculosis infection may involve the increased production of nitric oxide and cathelicidin due to the up-regulated expression of the vitamin D receptor (VDR), though this proposed mechanism remains controve…
Host defense peptides are effector molecules of the innate immunity that possess antimicrobial and health-promoting properties. Due to their potential therapeutic activities, host defense peptides are being explored as alternatives for antibiotics. T…
OBJECTIVE: To investigate the effect of antibacterial peptide hCAP18/LL-37 on ovarian cancer microenvironment and the regulatory mechanism of its expression. METHODS: We assessed the effect of macrophage-promoted ovarian cancer cells invasion using B…
OBJECTIVE: To investigate the effect of antimicrobial peptide cathelicidin secreted by non-tumorous cells in lung tumor growth. METHODS: CRAMP(-/-) mice and WT mice were used to establish a lung cancer model via tail vein injection of Lewis lung carc…
BACKGROUND: An increase in Staphylococcus aureus skin colonization in atopic dermatitis patients resulted from the reduction of cathelicidin production in these patients. Recently, an in vivo study demonstrated that vitamin D could stimulate cathelic…
BACKGROUND: The aim of this study was to evaluate the effect of 25-hydroxyvitamin D [25(OH)D] and cathelicidin levels on pelvic inflammatory disease [PID] in reproductive aged women. METHODS: A total of 81 reproductive aged women, 43 with PID and 38…
PEGylating is an effective way for prolonging the half-time period and decreasing the immunogenicity of protein drugs. With experiments of single factor, it was proved that the optimal processes for PEGylating the fused protein of LL-37 and interfero…
The interaction between arenicin-1, that is an antimicrobial peptide from polychaeta Arenicola marina, and human complement system protein C1q was studied using enzyme-linked receptor sorbent assay and ELISA. We revealed that arenicin-1 and C1q form…
Leukodystrophies are inherited disorders whose primary pathophysiology consists of abnormal deposition or progressive disruption of brain myelin. Leukodystrophy patients manifest many of the same symptoms and medical complications despite the wide sp…
BACKGROUND: Understanding the causes and timing of death in extremely premature infants may guide research efforts and inform the counseling of families. METHODS: We analyzed prospectively collected data on 6075 deaths among 22,248 live births, with…
BACKGROUND: Data on the influence of obesity on atherosclerosis in Hispanics are inconsistent, possibly related to varying cardiometabolic risk among obese individuals. We aimed to determine the association of obesity and cardiometabolic risk with su…
We have conducted a comparative analysis of the work ability index (WAI) application in evaluation of the effectiveness of small peptides (cytogens) used as geroprotectors in the system of preventive medical nutrition of those working with occupation…
AIMS: The pathology of stroke consists of multiple pro-death processes, and CD36 has been suggested as a multimodal target to reduce oxidative stress and inflammation in ischemic stroke. Using CD36-deficient mice and SS-31, a cell permeable tetrapept…
Sepsis-associated encephalopathy (SAE) is associated with increased mortality, morbidity, and long-term cognitive impairments. Its pathophysiology remains to be determined and an effective pharmacologic treatment is lacking. The goal of this study wa…
The impact of coronary artery stenosis (CAS) on renal injury is unknown. Here we tested whether the existence of CAS, regardless of concurrent atherosclerosis, would induce kidney injury and magnify its susceptibility to damage from coexisting hypert…
The contractile performance of skeletal muscle declines during intense activities, i.e. fatigue develops. Fatigued muscle can enter a state of prolonged low-frequency force depression (PLFFD). PLFFD can be due to decreased tetanic free cytosolic [Ca(…
Topics included a new agent to lower cholesterol and the use of cangrelor, bivalirudin, unfractionated heparin, ticagrelor, and Bendavia for acute coronary syndromes.
