Background: Dendritic cells (DCs) are professional antigen presenting cells (APCs), and there is considerable interest in their application as a cellular adjuvant for cancer immunotherapy.  Previous studies indirectly demonstrated that DCs were able to take up tumor lysate (crude soluble tumor antigens) and also cross-present tumor associated antigens (TAA) which elicits anti-tumor immune respo...

Since cheese is poor in energy for bacterial growth, it believed that non-starter lactic acid bacteria growth and flavour development are supported by the nutrients from lysis of starter culture. This study was performed to investigate dynamics interaction between strains cheese. A culture lysate prepared enzymatic digestion tested as a substrate Lactobacillus sp. strains. The two Lactococcus l...

In this research, we investigated the cytotoxic mechanisms of Cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.This micro algae is responsible for a severe and widespread harmful algal bloom in the Persian Gulf and Gulf of Oman (2008-2009). Isolated hepatocytes were obtained by collagenase perfusion of Sprague-Dawley rat liver.According to our results, incubation of algal...

Abundant erythrocytes remain and lyse partially in the subarachnoid space after severe subarachnoid haemorrhage (SAH). But the effect of subarachnoid erythrocyte lysate on brain injury is still not completely clear. In this study, autologous erythrocytes (the non-lysate group) and their lysate (the lysate group) were injected separately into the cistern magna of rabbits to induce a model of exp...

Previous investigations suggested that elastolytic activity found in platelets could be due to contamination by neutrophil elastase. In the present study, the lysate of blood platelets free of detectable neutrophils was examined for elastase-like activity using tertiary-butyloxycarbonyl (tBOC)-ala-ala-pro-ala-aminomethyl coumarin (I), tBOC-ala-ala-pro-val-aminomethyl coumarin (II), and succinyl...

background and objectives: glycoprotein 96 is the primary chaperone of the endoplasmic reticulum. immunization with it induced potent cytotoxic t lymphocyte responses to intracellular bacteria. s. typhimurium is a facultative intracellular bacterium and acquired resistance against this bacterium mainly depends on activity of cytotoxic t cells. this study aimed to evaluate the capacity of glycop...

Lake sediments hold a wealth of information from past environments that is highly valuable for paleolimnological reconstructions. These studies increasingly apply modern molecular tools targeting sedimentary DNA (sedDNA). However, sediment core sampling can be logistically difficult, making immediate subsampling sedDNA challenging. Sediment cores are often refrigerated (4 °C) weeks or months be...

Electroporation of dendritic cells (DCs) with tumor lysate elicited greater antitumor responses in vitro and in vivo, using less lysate than standard coincubation. Electroloaded DCs had normal surface marker expression and matured into competent antigen-presenting cells. In a renal carcinoma (RENCA) model, mice were pretreated with lysate-loaded DCs before tumor challenge. Mice that received DC...
