The immunomodulatory medicinal plants in pharmacognosy are relatively recent. In a number of disease situations, the immune response is impaired. Thus, either activating or inhibiting can be valuable treatment for maintaining disease-free state. Immunomodulators used chemotherapy. Even while system iscapable immunity and combating infections, germs viruses impair it.If our operating properly, w...

RSV infections are a major burden in infants less than 3 months of age. Newborns and infants express a distinct immune system that is largely dependent on innate immunity and passive immunity from maternal antibodies. Antibodies can regulate immune responses against viruses through interaction with Fc gamma receptors leading to enhancement or neutralization of viral infections. The mechanisms u...

Word Health Organization recommends exclusive breastfeeding. It is the ideal source of nutrition for neonates and infants. In addition, it contains antibodies, cytokines, antimicrobial substances, specific immunity cells. known to have a protective effect against most infections. However, there are also studies showing no preventive on urinary tract The present study aimed show association betw...

BACKGROUND Protective immunity to malaria is acquired after repeated infections in endemic areas. Asymptomatic multiclonal P. falciparum infections are common and may predict host protection. Here, we have investigated the effect of clearing asymptomatic infections on the risk of clinical malaria. METHODS Malaria episodes were continuously monitored in 405 children (1-6 years) in an area of m...

Trained immunity refers to a hyperresponsive functional state of the innate immune system, which is induced by certain stimuli, such as infections or vaccination. plays key part in variety diseases, including cancer and inflammation, regulated through epigenetic metabolic reprogramming haematopoietic stem progenitor cells bone marrow, giving rise hyperactive myeloid cells. Nanomaterials inheren...

In most natural infections or after recovery, small numbers of Leishmania parasites remain indefinitely in the host. Persistent parasites play a vital role in protective immunity against disease pathology upon reinfection through the process of concomitant immunity, as well as in transmission and reactivation, yet are poorly understood. A key question is whether persistent parasites undergo rep...

abstract background and aims: medical students are exposed to various infectious diseases during their clinical training period, including measles and rubella. in iran, to control the outbreaks of measles and rubella a mass vaccination campaign was conducted on 2003. the present investigation evaluates immunity to measles and rubella in a group of babol medical students and determines the preva...

Nature has provided us with infections - acute and chronic - and these infections have both harmful and beneficial effects on the human system. Worldwide, a number of chronic infections are associated with a risk of cancer, but it is also known that cancer regresses when associated with acute infections such as bacterial, viral, fungal, protozoal, etc. Acute infections are known to cure chronic...

After infections, malignancies, lymphomas especially, are the second most frequent cause of death in patients with inborn errors immunity. Factors predetermining appearance and aggressiveness include gene defects, defects immune surveillance regulation as well infections oncogenic viruses. Aggressive non-Hodgkin lymphomas, mostly diffuse large B-cell Bukit subtypes predominant deoxyribonucleic ...

Europe (8), resident populations in these countries have been exposed to these virus lineages more frequently than populations in Asia, and therefore may have acquired a greater degree of preexisting cross-reactive immunity to pandemic (H1N1) 2009 virus. A recent review of human swine infl uenza infections suggests that they may not be uncommon (9), although the true incidence of human infectio...
