The smallpox vaccine represents the earliest attempt in engineering immunity. The recent success of chimeric antigen receptor T cells (CAR-T cells) in cancer once again demonstrates the clinical potential of immune engineering. Inspired by this success, diverse approaches have been used to boost various aspects of immunity: engineering dendritic cells (DCs), natural killer (NK) cells, T cells, ...
The immune system works in coordination with other structures the body to prevent infections from occurring and fight existing infections. plays a role formation regulation of almost every disease therefore has very important place for human health. Researches show that internal external factors can affect immunity be effective protecting against diseases healing process. In this review, nutrit...

Flagellin (mol.wt. 40,000) from S. adelaide organisms and a series of acetoacetyl derivatives of flagellin were tested for their ability to induce humoral and cell-mediated immunity in adult rats. It was found that unmodified flagellin was an excellent inducer of antibody formation but a poor inducer of delayed-type hypersensitivity. In contrast, increasing acetoacetylation steadily destroyed t...
BACKGROUND One of the most commonly applied protectotype vaccination protocol against infectious bronchitis (IB) in broiler chickens in the EU is simultaneous or alternate use of Ma5 and 4/91 vaccine strains. After IB vaccination and infection, systemic and upper respiratory tract (URT), humoral and cell-mediated immunity (CMI), are stimulated. The level of this stimulation correlates with the ...
Since 1800, it is known that fungican invade human tissues and from 1900, there is a great deal of information about incidence and epidemiology and geographic distribution and fungal infections.Because of increased incidence of fungal infections on recent years and importance of these organisms in producing of systemic and muco- cutaneous diseases, many investigations are performed about these ...
The effects of methanolic extract and leaf powder of Artemisia annua were studied on performance, cellular and humoral immunity in 240 Cobb broiler chicks in a completely randomized design. Control group did not receive any treatment. The chicks in the second and third groups were fed with feed which contained 2000 and 4000 ppm plant extract in diet and in the groups 4, 5 and 6 chicks received ...
BACKGROUND Vaccination against hepatitis B virus infection (HBV) is safe and effective; however, vaccine-induced antibody level wanes over time. Peak vaccine-induced anti-HBs level is directly related to antibody decay, as well as risk of infection and persistent carriage despite vaccination. We investigated the role of host genetic factors in long-term immunity against HBV infection based on p...
BACKGROUND The aging process can lead to a decline in cellular immunity. Therefore, the elderly could benefit from safe and effective interventions that restore cellular immune functions. OBJECTIVE We determined whether dietary supplementation with the known immunostimulating probiotic Bifidobacterium lactis HN019 could enhance aspects of cellular immunity in elderly subjects. DESIGN Thirty...
This scientific report describes the effect of feeding detoxified karanj seed cake as protein replacement of soya bean meal on immunity and pathology in growing lambs. Twenty-four male lambs, 4-6 months of age were divided into four groups of six each and fed with different levels of detoxified karanj seed cake (dKC 0%, dKC 25%, dKC 50%, dKC 75%) for 140 days. Effect on humoral and cell mediate...
