A central element of the immune system has remained constant through more than 400 million years of evolution, according to new research at National Jewish Health. In the September 29, 2011, online version of the journal Immunity, the researchers report that T-cell receptors from mice continue to function even when pieces of shark, frog and trout receptors are substituted in. The function of the chimeric receptors depends on a few crucial amino acids, found also in humans, that help the...

(Ivanhoe Newswire) -- Stanford researchers have created the first human heart cells that can be paced with light, providing new insight into the heart's function. To create the light-responsive heart cells, the investigators first inserted DNA encoding a light-sensitive protein -- known as ChR2 -- into human embryonic stem cells. ChR2 controls the flow of electrically-charged ions into the cell. The primary ion for heart cells is sodium, which initiates the electrochemical cascade that...

Our livers can fight back against the immune system–reducing organ rejection but also making us more susceptible to liver disease. Scientists at the Centenary Institute in Sydney have seen for the first time (in mice) how the liver goes independent, engulfing and destroying the body's defence troops–T-cells. Their discovery, published overnight in PNAS (Proceedings of the National Academy of Sciences), opens the way to both new approaches to transplant rejection, and to the...

Image 1 - Biochemical Cell Signals Quantified For The First Time
2011-09-18 06:16:17

  Just as cell phones and computers transmit data through electronic networks, the cells of your body send and receive chemical messages through molecular pathways. The term “cell signaling” was coined more than 30 years ago to describe this process. Now, for the first time, scientists have quantified the data capacity of a biochemical signaling pathway and found a surprise — it´s way lower than even an old-fashioned, dial-up modem. “This key...

When It Comes To Speaking Out, Cells Wait Their Turn

  Revealing how cells communicate, Tel Aviv University research could lead to new cancer drugs and more Cell communication is essential for the development of any organism. Scientists know that cells have the power to "talk" to one another, sending signals through their membranes in order to "discuss" what kind of cell they will ultimately become – whether a neuron or a hair, bone, or muscle. And because cells continuously multiply, it's easy to imagine a cacophony of...

Study finds KN1 trafficking through tiny channels called plasmodesmata cannot occur without chaperonins Like all living things, plants depend for their growth and sustenance on elaborate signaling networks to maintain stem cells, cells that have an almost magical regenerative capacity. The signals sent through these networks convey an incredible diversity of instructions, which make it possible for plants to follow genetic and cellular programs regulating growth, shape, and energy...

Innate memory provides protection against vaccinia Researchers have demonstrated that cells of the innate immune system are capable of "memory", and of mounting rapid protection to an otherwise lethal dose of live vaccinia virus. The study, published in the Open Access journal PLoS Pathogens on August 4th, challenges previous thought that only B cells and T cells can store memory to ward off future infection. The finding, by researchers from Beth Israel Deaconess Medical Center, Harvard...

How do cells know where to position themselves and where to accumulate in order to carry out their functions correctly within each organ? Researchers with the Colorectal Cancer Lab at IRB Barcelona have revealed the molecular mechanisms responsible for organizing the intestinal epithelium into distinct comportments, defined by frontiers or territories. The study, headed by Eduard Batlle, coordinator of the Oncology Programme at IRB Barcelona and ICREA Research Professor, is published in...

FINDINGS: Using two distinct methods, Whitehead Institute researchers have successfully and consistently manipulated targeted genes in both human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells (adult cells that have been reprogrammed to an embryonic stem cell-like state). In one case, scientists employed proteins known as zinc finger nucleases (ZFNs) to change a single base pair in the genome, allowing them either to insert or remove mutations known to cause early-onset...

Researches near goal of using a patient's own cells to make stem cells that can replace lost or diseased tissue Scientists at the Salk Institute for Biological Studies have developed an improved technique for generating large numbers of blood cells from a patient's own cells. The new technique will be immediately useful in further stem cell studies, and when perfected, could be used in stem cell therapies for a wide variety of conditions including cancers and immune ailments. "There are...

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...

cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
