objective: different signaling pathways have been identified that are involved in the cellular response to opiates. the mitogen-activated protein kinase pathway is one of the most important signaling pathways underlying the neuronal response to opiates. micrornas (mirnas) are considered to be post-transcriptional regulators of gene expression with paramount significance, which plays key roles i...
objective: infectious microorganisms are major sources of illness and death worldwide, and the leading cause of death in neonates. effective vaccination of this age group is of particular importance. the lack of a response and greater susceptibility to tolerance are two major features that limit the effectiveness of vaccines in neonates. in this study we compare the cellular immune response gen...
propoxure (ppx) is a well-known carbamate insecticide, which has been used for several decades in the world and iran in agriculture and public health programs. however, there is no clear investigation toward its immunotoxicity as yet. in this study, we examined the effects of subchronic i.p. exposure of ppx on humoral (pfc & ha) and cellular (dth) responses, and also monitored t-cell subtypes u...
Effect of different levels of date waste were studied on performance and immune responses of 240 Ross 308 broiler chicks in a completely randomized design with 5 treatments and 4 replicates and 12 birds in each replicate. The whole date waste were analyzed for chemical compositions and gradual levels of 0 (control), 5, 10, 15 and 20 percent of that were included into the diets which fed broiler...
Background: Elevated level of plasma homocysteine has been related to various diseases. Patients with hyperhomocysteinemia can develop hepatic steatosis and fibrosis. We hypothesized that oxidative stress induced by homocysteine might play an important role in pathogenesis of liver injury. Also, the cellular response designed to combat oxidative stress is primarily controlled by the transcripti...
objective: several vaccines against hiv have been investigated but none has been approved as an effective hiv vaccine. an approach that could induce stronger immune response against the pathogen is utilizing a multi-epitopic vaccine. this strategy was used in the design of several vaccines and resulted in improved immune responses. materials and methods: in this study a multi-epitopic fusion p...
