Immunology and Development

Immunology of aging and cancer development.

The incidence and prevalence of most cancers increase with age. The immune system is a unique mechanism of defense against pathogens and possibly cancers, however there is a body of evidence that the immune system of the aged is eroded, a phenomenon termed immunosenescence. Each arm of the immune system, innate and adaptive, is altered with aging, contributing to increased tumorigenesis. Relate...

Ontology development for biological systems: immunology

UNLABELLED We recently implemented improvements to the representation of immunology content of the biological process branch of the Gene Ontology (GO). The aims of the revision were to provide a comprehensive representation of immunological processes and to improve the organization of immunology related terms in the GO to match current concepts in the field of immunology. With these improvement...

Immunology and Pathology: Poultry Immunology and Pathology

Immunomodulators like β-glucans have attracted considerable attention as potential alternatives to the prophylactic use of antibiotics. Despite increasing research, little is known about their regulatory influence on immune function in poultry. Two studies were conducted to evaluate the effects of a yeast-derived β-glucan (Auxoferm YGT) on gene expression of T helper cytokines in the intestine....
