Background and Aim: Regarding to various problems in the activation of dendritic cells and immune system’s responses, finding of a safe, effective and applicable agent is highly desirable. Chitosan is an effective gene delivery agent and also a part of nanoscaffolds. In the present study,chitosan nanopolymers effect on dendritic immune cells were assessed. Materials and Methods: In this experim...
Developing oocytes produce materials that will support early embryonic development then cease transcription before fertilization. Later, a distinct transcription program is established in the embryo. Little is understood about how these global gene regulation transitions are effected. We have investigated in C. elegans how oocyte transcription is influenced by maturation, a process that release...
Promastigote form of Leishmania, an intracellular pathogen, delays phagosome maturation and resides inside macrophages. But till date limited study has been done to manipulate the phagosomal machinery of macrophages to restrict Leishmania growth. Attenuated Leishmania strain exposed RAW 264.7 cells showed a respiratory burst and enhanced production of pro-inflammatory mediators. The augmentatio...
Maturation-promoting factor causes germinal vesicle breakdown when injected into Xenopus oocytes and can induce metaphase in a cell-free system. The cell-free assay was used to monitor maturation-promoting factor during its purification from unfertilized Xenopus eggs. Ammonium sulfate precipitation and six chromatographic procedures resulted in a preparation purified greater than 3000-fold that...
VEGF (vascular endothelial growth factor) is the master regulator of blood vessel growth. However, it displayed substantial limitations when delivered as a single gene to restore blood flow in ischaemic conditions. Indeed, uncontrolled VEGF expression can easily induce aberrant vascular structures, and short-term expression leads to unstable vessels. Targeting the second stage of the angiogenic...
