Lentiviral vectors (LVs) are promising delivery systems for gene therapy. To enhance the efficiency of target cell transduction by LVs, protocols often include the addition of culture additives. In this study, the cationic amphipathic peptide LAH4-L1 (KKALLAHALHLLALLALHLAHALKKA), a DNA transfection agent, was evaluated for its capacity to improve LV infectivity in cell lines and primary cells. ...
Immunotherapy has emerged as an important approach for combating cancer. Dendritic cell (DC)-based vaccines are a promising form of immunotherapy because of their ability to induce tumor antigen-specific T cells. Although there are many methods for preparing DC-based vaccines using full-length proteins, cell-penetrating peptides (CPP) have shown success in their ability to deliver whole protein...
The histidine-rich amphipathic peptide LAH4 has antibiotic and DNA delivery capabilities. The peptide has a strong affinity for anionic lipids found in the outer membrane of bacterial membranes. A role for anionic lipids in release of cationic plasmid-containing complexes has been proposed previously, and disruption of membrane asymmetry and presentation of phosphatidylserine (PS) in the membra...
Besides being a useful tool in research, gene transfer has a high potential as treatment for a variety of genetic and acquired diseases. However, in order to enable a gene to become a pharmaceutical, efficient and safe methods of delivery have to be developed. We recently found that cationic amphipathic histidine-rich peptide antibiotics can efficiently deliver DNA into mammalian cells. Our lea...
با توجه به افزایش پیدایش سلول های سرطانی مقاوم به عوامل شیمی درمانی مرسوم، طراحی و گسترش داروهای ضد سرطانی با مکانیسم عمل جدید یک نیاز مبرم در جهت تخریب سلول های سرطانی با حداقل سمیت و اثرات جانبی می باشد. در سال های اخیر پپتیدهای ضدمیکروبی (amps) به واسطه ی توانایی درمانیشان جهت تشکیل اساس عوامل درمانی جدید توجه بسیاری را جلب نموده اند. در این تحقیق ما در طی 3 بخش برهمکنش پپتید ضدمیکروبی سنتز ...
