Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

Bacteria found in the mouth can block the HIV virus

Certain strains of bacteria that occur naturally in the human mouth can snare the HIV virus and even cells it has infected, according to researchers at the University of Illinois at Chicago College of Dentistry. They report their findings today at the 104th General Meeting of the American Society for Microbiology.

Toxoplasma gondii discovery may help fight against malaria

University of North Carolina at Chapel Hill scientists have discovered a protein in the cell wall of parasites that’s crucial to the molecular mechanism allowing them to move between cells, survive and cause disease.

Possible new second-generation multiple sclerosis therapy

Scientists from Genencor International, Inc., have demonstrated in an in vivo model that a new variant of recombinant interferon-beta reduces the immunological response to the protein.

Researchers to develop a highly sensitive, portable method of detecting bioterror agents like anthrax

Their method uses "Cellular Analysis and Notification of Antigen Risks and Yields" (CANARY) cells, which are immune-system cells engineered to contain a fluorescent protein naturally found in jellyfish. CANARY cells have the immune system's ability to detect specific disease-causing agents, lighting up when they recognize a pathogen.

Trial shows Daclizumab therapy improves multiple sclerosis outcome

A small clinical trial of patients with multiple sclerosis (MS) who did not respond to interferon alone found that adding the human antibody daclizumab improved patient outcome. Patients who received the combined therapy had a 78 percent reduction in new brain lesions and a 70 percent reduction in total lesions, along with other significant clinical improvements.

Researchers have isolated a protein receptor in chickens responsible for transferring antibodies from mother to offspring

Howard Hughes Medical Institute (HHMI) researchers have isolated a protein receptor in chickens that is responsible for transferring antibodies from mother to offspring - a function critical to bestowing a temporary immunity that protects the young against infection until their own immune systems begin functioning.

Compound Cilantro found in salsa kills harmful Salmonella bacteria

Researchers have identified a compound in cilantro, a key flavor component of salsa and a variety of other dishes, that kills harmful Salmonella bacteria and shows promise as a safe, natural food additive that could help prevent foodborne illness, according to a joint study by U.S. and Mexican researchers.

New series of clinical standards to diagnose heart attacks

Diagnosing heart attacks will become a more precise science thanks to the first of a new series of clinical standards just issued by the National Institute of Standards and Technology (NIST). Standard Reference Material (SRM) 2921 (human cardiac troponin complex) will help manufacturers develop and calibrate assays that measure specific protein concentrations in patient blood samples to determine whether a heart attack has occurred.

Cystic Fibrosis Foundation Therapeutics awards $21 million to Vertex

Vertex Pharmaceuticals Incorporated has announced that it has expanded its drug discovery and development collaboration with Cystic Fibrosis Foundation Therapeutics, Inc. (CFFT), the nonprofit drug discovery and development affiliate of the Cystic Fibrosis Foundation.

Research shows that treatment with nitric oxide after storage may dramatically improve the viability of transplanted livers

About 5,000 liver transplants are performed annually in the United States, and a key factor ensuring success is maintaining a healthy donor organ that can function effectively in the recipient. However, transplanted livers typically incur substantial damage when blood flow is restored to the organ after the transplant.

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals. The discovery was made by applying the latest laboratory methods to a strain of mice restored from embryos frozen since the early 70s.

An antibiotic, Tigecycline produces 74 percent cure rate in cSSSI patients

An antibiotic, currently being tested in clinical trials, produced a 74 percent cure rate for hospitalized patients with possibly life-threatening, complicated skin and skin structure infections (cSSSI).

Using gene therapy to fight rheumatoid arthritis

Guided by a similar principle, arthritis researchers at the University of Florida and Harvard University hope to use gene therapy to help joint cells pump out a harmless protein that parks in receptor sites, leaving a notorious inflammatory agent “circling the lot” and unable to cause pain, swelling and possible joint damage.

Are we as crazy as mad cows?

When proteins in our body work properly, we can see, smell, consume and digest food, grow muscle and brain cells. But when these infinitely useful biological building blocks fail, the most pernicious diseases arise. Susan Lindquist has scrutinized the complex origami-like shapes of proteins and come to understand how structural mistakes can lead to a frightening class of neurodegenerative disorders, including “Mad Cow Disease.”

Natural biological process by which yeast cells dismantle amyloid fibers

Amyloid fibers, those clumps of plaque-like proteins that clog up the brains of Alzheimer's patients, have perplexed scientists with their robust structures. In laboratory experiments, they are able to withstand extreme heat and cold and powerful detergents that cripple most other proteins.

Protein that appears to play a key role in Alzheimer's disease

A protein that allows human cancer to resist multiple anticancer drugs also appears to play a key role in Alzheimer's disease, according to research conducted at Fox Chase Cancer Center. The protein, active in brain tissue, could be a target for new drugs to treat patients with Alzheimer's.

Cell division can be halted in multiple ways, with implications for cancer

Brown University researchers have found that there are multiple independent ways to stop cell division, a phenomenon that prevents the spread of genetic mutation, which can make cells cancerous. Results of this research, along with an accompanying editorial, were published in the current issue of the journal Molecular Cell.

Scientists have sped up a common jumping gene found in the human genome

Johns Hopkins scientists have transformed a common "jumping gene" found in the human genome into one that moves hundreds of times more often than normal in mouse and human cells.

Study has important implications for African Americans who suffer from high blood pressure

A new study has important implications for the millions of African Americans who suffer from high blood pressure. The study, AADVANCE, shows Diovan HCT(R) (valsartan and hydrochlorothiazide) lowers blood pressure in African Americans to aggressive recommended target blood pressure goals as effectively as amlodipine.
