Upon fertilisation, a single cell is formed when egg and sperm fuse. Our entire body, with more than 200 specialised cell types and billions of cells are formed from this single cell. It is a scientific mystery how the early stem cells know what cell type to become, but a precise timing of the process is crucial for correct development and function of our body. Researchers across the world chase knowledge about our stem cells, as this knowledge holds great promises for development of...

Cells that die naturally generate a lot of internal debris that can trigger the immune system to attack the body, leading to diseases such as lupus. Now Georgia Health Sciences University researchers report that an enzyme known to help keep a woman's immune system from attacking a fetus also helps block development of these autoimmune diseases that target healthy tissues, such as DNA or joints. The findings point toward new treatment strategies for autoimmune diseases, which are on the...

2,000-year-old herb regulates autoimmunity and inflammation For roughly two thousand years, Chinese herbalists have treated Malaria using a root extract, commonly known as Chang Shan, from a type of hydrangea that grows in Tibet and Nepal. More recent studies suggest that halofuginone, a compound derived from this extract's bioactive ingredient, could be used to treat many autoimmune disorders as well. Now, researchers from the Harvard School of Dental Medicine have discovered the...

Immunological diseases, such as eczema and asthma, are on the increase in westernised society and represent a major challenge for 21st century medicine. A new study has shown, for the first time, that growing up on a farm directly affects the regulation of the immune system and causes a reduction in the immunological responses to food proteins. The research, led by the University of Bristol's School of Veterinary Sciences, found that spending early life in a complex farm environment...

SENP1 prevents crucial gene-activator STAT5 from becoming trapped in nucleus When SUMO grips STAT5, a protein that activates genes, it blocks the healthy embryonic development of immune B cells and T cells unless its nemesis breaks the hold, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports today in Molecular Cell. "This research extends the activity of SUMO and the Sentrin/SUMO-specific protease 1 (SENP1) to the field of immunology, in...

Leukemic cutaneous T-cell lymphoma (L-CTCL) is a leukemia arising from T-cells, a type of white blood cell. This cancer can involve the skin and other organs, and patients often die within three years. Rachael A. Clark, MD, PhD, BWH assistant professor of dermatology and associate dermatologist and Thomas Kupper, MD, BWH Department of Dermatology chairman and their colleagues now report a new study that low-dose Campath (alemtuzumab) not only treats patients with L-CTCL but does so without...

Multicellular organisms must have a means for cells to communicate with one another. Past research has shown that plants possess the ability to directly transfer materials between adjacent cells, through holes in their cell walls called plasmodesmata (PD). Now, a study published by Cell Press in the December issue of the journal Developmental Cell reveals one way to control the size of these PD channels, to prevent or allow the passage of important signals between cells, during plant...

A protein called enhanced disease susceptibility 1 (EDS1) plays a central role in plants' ability to defend themselves from pathogens. But in the almost two decades since it was discovered, how EDS1 works at the molecular level has been a mystery. Solving the mystery will help scientists enhance disease resistance in crops. Two papers published in the Dec. 9 issue of Science (http://www.sciencemag.org/magazine) demonstrate how EDS1 activates different components of the plant immune system,...

Thymus
2013-03-04 12:56:08

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...
