Characterization of CD4(+) CTLs ex vivo.
The cytotoxic potential of CD8(+) T cells and NK cells plays a crucial role in the immune response to pathogens. Although in vitro studies have reported that CD4(+) T cells are also able to mediate perforin-mediated killing, the in vivo existence and relevance of cytotoxic CD4(+) T cells have been the subject of debate. Here we show that a population of CD4(+) perforin(+) T cells is present in ...
متن کاملLoratadine- Loaded Thermoresponsive Hydogel : Characterization and Ex-vivo Rabbit Cornea Permeability Studies
Poor bioavailability of ophthalmic drops is mainly due to drainage through the nasal-lacrimal duct and a very low permeability through corneal epithelium. The aim of our study was to prepare and characterize an ocular hydrogel of loratadine, as an example of a lipophilic drug, to increase drug concentration and residence time at the site of action in the eye. In this study,a 23full factorial de...

متن کاملAntifungal potential of tolnaftate against Candida albicans in the treatment of onychomycosis: development of nail lacquer and ex vivo characterization
Onychomycosis constitutes the most common fungal infection of nail affecting finger and toe nails as well. Antifungals found to be effective in the treatment of onychomycosis. However, transport of oral antifungal agents exhibits more toxicity and requires longer treatment period. Medicated nail lacquers proved to cause lesser toxicity and required shorter treatment period. It provides not only...
متن کاملCharacterization of Plaque with SWI Approach: Ex vivo Study
Purpose Major atherosclerotic plaque components (lipid, calcification, intraplaque hemorrhage or IH) were able to be identified with an established multi-contrast plaque imaging approach in MRI [1]. However, interscan patient motion, partial volume effect, and flow artifacts may render the accurate segmentation of plaque components difficult. Susceptibility-weighted imaging (SWI) shows capabili...
