Modeling pathogen responses
The search for a vaccination against HIV has been in progress since 1984, with very little success. Traditional methods used for identifying potential cellular targets can be very costly and time-consuming.   view more (2007-10-12)

The CReSA is working on a new strategy to combat spongiforms
Researchers at the Animal Health Research Centre (CReSA) are developing immunotherapeutical strategies against diseases produced by prion, such as Bovine Spongiform Encephalitis.   view more (2006-11-01)

Atherosclerosis studied at the cellular level
A McMaster University study on atherosclerosis will be featured on the cover of the December issue of the high impact American Heart Association scientific journal, Arteriosclerosis, Thrombosis and Vascular Biology.   view more (2005-12-02)

New brain cells implicated in machinery of cannabinoid signaling
The brain cells called astrocytes, and not just neurons, are sensitive to the substances called cannabinoids-the active chemicals in marijuana.   view more (2008-03-27)

Animal study suggests inadequate sleep may exacerbate cellular aging in the elderly
Researchers at the University of Pennsylvania School of Medicine have shown that the unfolded protein response, which is a reaction to stress induced by sleep deprivation, is impaired in the brains of old mice.   view more (2008-06-30)

A potential approach to treatment of hepatitis B virus infection
Eukaryotic cells employ multiple strategies of checkpoint signaling and DNA repair mechanisms to monitor and repair damaged DNA.   view more (2008-09-10)

Human Cytomegalovirus May Be Involved In Colorectal Cancer (p 1557)
Preliminary findings of a study in this week's issue of THE LANCET suggest that a common human virus may play a part in the cellular processes involved in the development of colorectal cancer. Colorectal cancer is the second most frequent cause of death from cancer in many developed countries;... view more (2002-11-13)

Executable biology -- Computer science sheds light on animal development
By applying the techniques of computer engineering to a mechanistic diagram describing the development of the Nematode C. elegans, a group of researchers in Switzerland has been able to tease out what laboratory experiments have not - how and when the crucial cross-talk between cellular signaling... view more (2007-05-18)

Molecular motor works by detecting minute changes in force
Researchers at the University of Pennsylvania School of Medicine discovered that the activity of a specific family of nanometer-sized molecular motors called myosin-I is regulated by force. The motor puts tension on cellular springs that allow vibrations to be detected within the body.   view more (2008-07-10)

Immune responses spread from one protein to another in type 1 diabetes
Type 1 diabetes (T1D) is caused by the immune system inappropriately attacking the cells in the pancreas that produce insulin, the hormone that controls blood sugar levels.   view more (2006-12-04)

If You Are Down, You May Be More Likely To Get Infections
The association between depression and immune response is not yet clear. The biological mechanisms by which depression alters the immune system is not yet understood. The purpose of this study was to investigate the longitudinal relationship between depressive symptoms and cellular immune response.... view more (2003-09-01)

A Novel Strategy for Combating Aids-Related Fungal Infections
Research at the Sir William Dunn School of Pathology has identified Dectin-1 as the beta-glucan receptor on immune cells. This finding may be of use in the prophylactic prevention of a variety of infections, especially in surgical patients, and in the treatment of cancer. The identification of... view more (2004-10-08)

Glue inside the cell: Ubiquitin builds up an immune response
Ubiquitin is a small protein, which can be attached to other cellular proteins, a process known as ubiquitination. Discoveries in the 1980 th on a key function of ubiquitination in the regulation of protein degradation where awarded with the Nobel Prize for chemistry in 2004.   view more (2007-10-22)

New epidemiological review finds no causal association between the use of cellular phones and cancer
The Swedish Radiation Protection Authority has engaged two internationally well-known epidemiologists to review published epidemiological studies on the relationship between the use of cellular telephones and cancer risk. They are Dr. John D. Boice, Jr. and Dr. Joseph K. McLaughlin from the... view more (2002-09-20)

Biodegradable microspheres deliver time release vaccines, stimulate different immune response
A new vaccine delivery system using microspheres of a biodegradable polymer may not only reduce the need for booster shots in some cases, but also appears to stimulate an immune response that traditional vaccines do not.   view more (2007-03-01)

A new brake on cellular energy production discovered
A condition that has to be met for the body to be able to keep warm, move and even survive is that the mitochondria - the cells' power stations - release the right amounts of energy.   view more (2007-07-27)

Unlocking biological secrets: Cornell scientists build 'nano-keys' to bind cell receptors and trigger allergic reactions
The tumblers of life continue to click as Cornell University researchers have fabricated a set of "nano-keys" on the molecular scale to interact with receptors on cell membranes and trigger larger-scale responses within cells - such as the release of histamines in an allergic response.   view more (2006-02-17)

Neurogenesis in the adult brain: The association with stress and depression
The brain is the key organ in the response to stress. Brain reactions determine what in the world is threatening and might be stressful for us, and regulate the stress responses that can be either adaptive or maladaptive.   view more (2008-07-09)

Nanoscale microscope sheds first light on gene repair
Proteins called H2AX act as "first aid" to DNA, among other roles. For the first time, scientists using the world's most powerful light microscope (the only one of its kind in the Americas) have seen how H2AX is distributed in the cell nucleus: in clusters, directing the first aid/repair... view more (2006-11-14)

Tattooing improves response to DNA vaccine
A tattoo can be more than just a fashion statement - it has potential medical value, according to an article published in the online open access journal, Genetic Vaccines and Therapy.   view more (2008-02-07)

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer, says Penn research team
Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.   view more (2007-12-18)

Atherosclerosis Could Be Linked To Premature Ageing (p 472)
A pilot study published in a research letter in this week's issue of The Lancet suggests that chromosomal changes associated with premature ageing may predispose individuals to atherosclerosis. Chromosomes end with telomeres, which shorten with cellular ageing; therefore, telomere length can be... view more (2001-08-08)

Molecular mechanism provides intra-cellular traffic signal
Researchers at the University of Illinois at Chicago have found that intra-cellular trafficking is tightly coordinated for maximum flow through cellular compartments - much as vehicles on a crowded road are allowed to pass quickly through a succession of green traffic lights.   view more (2006-10-18)

New understanding of parasite cell structures may provide treatments for serious tropical diseases
Don't even think about trying to pronounce it. Although it is found in many organisms including humans, glycosylphosphatidylinositol has remained a mouthful for laymen and a puzzle for scientists.   view more (2006-05-10)

Towards predicting late-stage radiation toxicity
Radiation is a brutal and in many cases necessary part of cancer therapy. More 50% of cancer patients receive radiotherapy as part of their treatment, and many experience concurrent negative side effects.   view more (2006-10-31)
