Can Inflammation Predict Heart Disease and Stroke?

Groundbreaking research may be able to help predict how likely it is that a person will have heart disease or a stroke in the future. Studies have linked inflammation to the risk of cardiovascular disease because of the association between the release of C-Reactive Protein (CRP) and heart disease.

What is C-Reactive Protein (CRP)?

The National Institute of Health explains that CRP is a protein that is released when there is inflammation present in the body. The liver produces the protein and a blood test can be done to find out how much CRP is present in a person’s body.

What is inflammation?

John W. Kimball maintains a website describing in depth how inflammation develops in the body. Inflammation develops as a result of injury to the body. It can often be recognized by swelling and redness at the site of inflammation and may be accompanied by pain. Although inflammation often occurs on the surface of the skin, it can also occur internally. (more…)

Scientists Identify Novel Pathway for T Cell Activation in Leprosy

*Findings may help lead to new treatments for infectious diseases, cancer*

UCLA researchers have pinpointed a new mechanism that potently activates T cells, the group of white blood cells that plays a major role in fighting infections.

The team specifically studied how dendritic cells, immune cells located at the site of an infection, become more specialized to fight the leprosy pathogen known as Mycobacterium leprae. Dendritic cells, like scouts in the field of a military operation, deliver key information about an invading pathogen that helps activate the T cells in launching a more effective attack. (more…)

Newly Found Protein Helps Cells Build Tissues

University biologists have found a new molecule in fruit flies that is key to the information exchange needed to build wings properly. They have also uncovered evidence that an analogous protein may exist in people and may be associated with problems such as cleft lip, or premature ovarian failure.

PROVIDENCE, R.I. [Brown University] — As they work together to form body parts, cells in developing organisms communicate like workers at a construction site. The discovery of a new signaling molecule in flies by Brown University biologists not only helps explain how cells send many long-haul messages, but also provides new clues for researchers who study how human development goes awry, for instance in cases of cleft lip and palate.

Curcumin Shows Promise in Attacking Parkinson’s Disease

EAST LANSING, Mich. — Curcumin, a compound found in the spice turmeric, is proving effective at preventing clumping of a protein involved in Parkinson’s disease, says a Michigan State University researcher.

A team of researchers led by Basir Ahmad, an MSU postdoctoral researcher, demonstrated earlier this year that slow-wriggling alpha-synuclein proteins are the cause of clumping, or aggregation, which is the first step of diseases such as Parkinson’s. A new study led by Ahmad, which appears in the current issue of the Journal of Biological Chemistry, shows that curcumin can help prevent clumping. (more…)

Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.

The technique could lead to affordable personalized medicine, potentially revealing predispositions for afflictions such as cancer, diabetes or addiction. (more…)

‘Bed-of-Nails’ Breast Implant Deters Cancer Cells

Researchers at Brown University have created an implant that appears to deter breast cancer cell regrowth. Made from a common federally approved polymer, the implant is the first to be modified at the nanoscale in a way that causes a reduction in the blood-vessel architecture that breast cancer tumors depend upon, while also attracting healthy breast cells. Results are published in Nanotechnology.

PROVIDENCE, R.I. [Brown University] — One in eight women in the United States will develop breast cancer. Of those, many will undergo surgery to remove the tumor and will require some kind of breast reconstruction afterward, often involving implants. Cancer is an elusive target, though, and malignant cells return for as many as one-fifth of women originally diagnosed, according to the American Cancer Society. (more…)

Yale researchers have discovered how megakaryocytes — giant blood cells that produce wound-healing platelets — manage to grow 10 to 15 times larger than other blood cells.

The findings, to be published March 13 in the journal Developmental Cell, also hint at how a malfunction in this process may cause a form of leukemia. (more…)

It Takes Two to Tango: Pairs of Entwined Proteins Handle The Stress

ANN ARBOR, Mich.— Imagine two tango dancers sweeping across the dance floor and suddenly encountering a slick spot. To avoid a slip or even a nasty tumble, the pair must work together to support one another and glide safely through the stressful moment.

In a similar way, a certain type of helper protein called a stress-specific molecular chaperone prevents its client proteins from collapsing during stressful situations by uncoiling a long, supportive arm that wraps around them, a University of Michigan-led research team has shown. (more…)
