Background: Problems of live and inactivated influenza vaccines such as, increasing emerge and re-emerge viruses with high human mortality, current epidemics of influenza and direct transmission of avian viruses to human, affect the vaccination program. DNA vaccines as third generation of vaccines is specially considered for control of influenza in human and poultry. The main advantage of these...
Background and purpose: In recent years nanotechnology has a significant impact on various fields of human life, especially in pharmaceutical and medical needs. Some biopolymers such as chitosan which is also biocompatible are low cost and abundantly found, so, their application for vaccine production is cost benefit. Trimethyl chitosan is a deacetylated derivative of chitosan that could be use...
aids (acquired immune deficiency syndrome), a result of human hiv (human immunodeficinency virus) infection, is one of the most troublesome world's health problems. extensive researches to find effective drugs for its treatment are running fast in huge capacities. imod (immuno-modulator drug) is the name of an herbal drug that has modulatory effects of immune system. as a goal of this research,...

Background: Cervical cancer is the most prevalent tumor in developing countries and the second most frequent cancer among female population worldwide. Specific human papillomaviruses and, most notably, HPV types 16 and 18 are recognized as being caus-ally associated with cervical carcinomas. The early HPV type 16 genes, E6 and E7, di-rectly participate in the in vitro transformation of primary ...
Prostatic carcinoma is the most commonly diagnosed tumor among men over 40 which results in over 30,000 deaths each year in the United States. Previous studies indicated that tumor cell lines produce and release several growth regulatory factors into their condition media and so far a number of human tumor cell-derived suppressor factors have been isolated that affect normal immune functions. I...
Background: In the last decade due to emerge and remerge of influenza viruses, quality improvement of vaccines to increase immune responses in target populations have been more necessary. The potential of biologic adjuvant to stimulate and induce immune system is the basis of modern researches in prevention and controlling program of infectious diseases. In this study, the effect of the coding ...
The Donath-Landsteiner reaction was studied using low and high titer antisera and purified antibody, normal and PNH erythrocytes, and human serum complement. The requirement for complement in both the cold and warm phases of the reaction depended upon the level of antibody used and the sensitivity of the cells to hemolytic antibodies. Complement was not necessary in the cold phase using PNH cel...
The human immune system is under great pathogen-mediated selective pressure. Divergent infectious disease pathogenesis across human populations combined with the overrepresentation of "immune genes" in genomic regions with signatures of positive selection suggests that pathogens have significantly altered the human genome. However, important features of the human immune system can confound sear...
