New research published in the Journal of Leukocyte Biology suggests that natural killer cells promote inflammatory responses in dry eyes at both the ocular surface and the eye-draining lymph nodes If you are one of the millions of people around the world who struggle with dry eye disease, good news is on the way. A new research discovery published in the Journal of Leukocyte Biology (https://www.jleukbio.org) offers hope for new drugs that treat the cellular cause of the disease rather than...

An article in Science Signaling by researchers at the RIKEN Research Center for Allergy and Immunology (RCAI) has clarified for the first time the mechanism governing differentiation of B cells into antibody-producing plasma cells. The finding establishes a role for the extracellular signal-regulated kinase (ERK) signaling pathway in B cell differentiation, a key step toward the development of B cell-targeted drugs for treatment of autoimmune diseases and allergies. As the only cells in the...

Our immune systems contain three fundamentally different types of cell:  B-cells, T-cells and the mysteriously named Natural Killer cells (NK cells), which are known to be involved in killing tumor cells and other infected cells.  Experiments to investigate the function of NK cells have proven difficult to interpret because the interactions between the various components of the immune system make it almost impossible to isolate effects of individual cell types.  This has...

First report of a recombinant human biotherapeutic active against leukemic stem cells Scientists at the Children's Center for Cancer and Blood Diseases and The Saban Research Institute of Children's Hospital Los Angeles today announced a breakthrough discovery in understanding how the body fights leukemia. They have identified a protein called CD19-ligand (CD19-L) located on the surface of certain white blood cells that facilitates the recognition and destruction of leukemia cells by the...

T-regulatory lymphocytes (Tregs) are a subset of T lymphocytes that are involved in the mechanism of immunotolerance to self- and allo-antigens. Activity of these cells is one of the mechanisms of immune evasion of tumors, which inhibits the antitumor activity of effector cells. Tregs are among the tumor-infiltrating lymphocytes and circulate in the peripheral blood. In various cancer types, increased prevalence of Tregs has been observed, and in some studies, this has been reported as a...

Immunologist Thomas L. Rothstein, MD, PhD, and his colleagues from The Feinstein Institute for Medical Research have staked their reputations on finding these so-called "B1 cells" that make "natural" protective antibodies and come online before the adaptive immune system is mature enough to start working. And that is precisely what they have done. Manhasset, NY (Vocus/PRWEB) January 21, 2011 It has long been thought that the human body contains innate immune defense B cells that are present...

The findings challenge long-held dogma in field of immunology A team of scientists from The Scripps Research Institute have uncovered a previously unknown regulatory mechanism in the body's response to eliminate pathogens, such as bacteria and viruses. The findings challenge a long-held dogma in the field of immunology and have potential implications for far-ranging topics from how vaccines should be administered to the origin of autoimmunity. The results of the study, led by Scripps Research...

Although human and chimpanzee immune systems have many identical components, this is not the case for the family of killer cell immunoglobulin-like receptors (KIR) controlling white blood cells known as natural killer (NK) cells. Published in the open-access journal PloS Genetics on November 4, a paper by Stanford University researchers describes qualitative KIR differences, acquired after humans and chimpanzees separated 6 million years ago and mainly a consequence of innovation in the human...

In order to track down pathogens and render them harmless, the immune system must be able to recognize myriad different foreign substances and react to them. Scientists at the Max Planck Institute of Immunobiology and the Centre for Biological Signalling Studies BIOSS at the University of Freiburg have discovered how the immune system's B-cells can be activated by numerous substances from our environment. The receptor molecules on the surface of the B-cells are only activated when the...

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...
