Newborn babies' immune system development and levels of vitamin D have been found to vary according to their month of birth, according to new research. The research, from scientists at Queen Mary, University of London and the University of Oxford, provides a potential biological basis as to why an individual's risk of developing the neurological condition multiple sclerosis (MS) is influenced by their month of birth. It also supports the need for further research into the potential...

Helper cells of the immune system can switch to become killer cells in the gut The fate of mature T lymphocytes might be a lot more flexible than previously thought. New research from the RIKEN Center for Allergy and Immunology (RCAI) in Japan and La Jolla Institute for Allergy and Immunology (LIAI) in the USA shows for the first time that mature CD4+ helper T lymphocytes can be re-programed to become killer-like CD8+ T lymphocytes and gain killing functions. The findings are reported...

A transcription factor called Lyl-1 is necessary for production of the earliest cells that can become T-cells, critical cells born in the thymus that coordinate the immune response to cancer or infections, said a consortium of researchers led by those from Baylor College of Medicine (www.bcm.edu) in a report in the journal Nature Immunology. These earliest progenitors (called early T lineage progenitor cells) are the first cells that can be identified as being on the road to becoming...

4 signaling substances control the transformation of T cells The thymus plays a key role in the body's immune response. It is here where the T lymphocytes or T cells, a major type of immune defense cells, mature. Different types of T cells, designated to perform specific tasks, arise from progenitor cells that migrate to the thymus from the bone marrow. Researchers at the Max Planck Institute of Immunology and Epigenetics in Freiburg have generated artificial thymus tissue in a mouse...

A new study provides evidence that a critical type of immune cell can develop in human tonsils. The cells, called T lymphocytes, or T cells, have been thought to develop only in the thymus, an organ of the immune system that sits on the heart. The study, led by researchers at the Ohio State University Comprehensive Cancer Center — Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC — James), could improve the understanding of T-cell cancers and...

In the latest issue of Nature, researchers at the Perelman School of Medicine at the University of Pennsylvania clarify the role of two proteins key to T-cell development. They found that one well-known protein called Notch passes off much of its role during T-cell maturation to another protein called TCF-1. T cells are required for many aspects of immunity, and understanding how these proteins influence the production of infection-fighting cells could improve treatments for immune-suppressed...

Scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ), jointly with colleagues in the United States, have found out that inflammations of the heart muscle are caused by attacks of a specific type of immune cells. These immune cells attack the body's own tissue because during their maturation they did not have the chance to develop tolerance against a protein that is only found in the heart muscle. An inflammation of the heart muscle, or myocarditis,...

Biologists have discovered that primitive, predatory lampreys have structures within their gills that play the same role as the thymus, the organ where immune cells called T cells develop in mammals, birds and fish. The finding suggests that in vertebrate evolution, having two separate organs for immune cell development -- the bone marrow for B cells and the thymus for T cells -- may have preceded the appearance of the particular features that mark those cells, such as antibodies and T cell...

A newly identified regulatory process affecting the biology of immune system T cells should give scientists new approaches to explore the causes of autoimmunity and immune deficiency diseases. In findings posted online ahead of publication in Proceedings of the National Academy of Sciences (PNAS), scientists at Cincinnati Children's Hospital Medical Center report a novel process of coordinated cellular communications vital to the maintenance of T cells. If the process breaks down, T cells...

UA research with mice indicates that immune deficiencies associated with weightlessness may pose a challenge to manned space missions to far-away destinations such as Mars. Astronauts are known to have a higher risk of getting sick compared to their Earth-bound peers. The stresses that go with weightlessness, confined crew quarters, being away from family and friends and a busy work schedule - all the while not getting enough sleep - are known to wreak havoc on the immune system. A research...

The thymus gland is an endocrine organ of the immune system located anteriolateral to the trachea and in between the lungs. Its primary function is to build T lymphocytes for the body’s immune system; therefore, it is most important during childhood and puberty, when it reaches its maximum size. After puberty, it will begin to atrophy and shrink in size. Old age generally brings about hypotrophy of the thymus. In children the thymus is grayish-pink in color and in adults it is yellow. On...
