CD4 T cells orchestrate inflammatory attack on the artery wall

Most people probably know that heart disease remains the nation's No. 1 killer. But what many may be surprised to learn is that cholesterol has a major accomplice in causing dangerous arterial plaque buildup that can trigger a heart attack. The culprit? Inflammatory cells produced by the immune system.

Catechins may help reduce neurological complications linked to HIV

Current drug therapy for patients with HIV is unable to control the complete replication of the virus in the brain. The drugs therefore do not have any effect against the complications associated with neurocognitive impairment in patients with HIV. New research by Joseph Steiner and colleagues from Johns Hopkins University has discovered that a group of plant polyphenols known as catechins, which naturally occur in green tea and the seed of the cacao tree, may help in the prevention of these neurological complications.

Study investigates ability of bifidobacteria to remove glycans from milk glycoproteins

A research team at the University of California, Davis, has found that important and resourceful bacteria in the baby microbiome can ferret out nourishment from a previously unknown source, possibly helping at-risk infants break down components of breast milk.

Glioblastoma patients with modified PTEN have resistance to EGFR inhibitors

Despite years of research, glioblastoma, the most common and deadly brain cancer in adults, continues to outsmart treatments targeted to inhibit tumor growth.

Scientists use supercomputers to reveal links between known risk factors and heart biology

About 25,000 Danes currently live with congenital heart defects. Both heredity and environment play a role for these malformations, but exactly how various risk factors influence the development of the heart during pregnancy has been a mystery until now.

Cathepsins may attack one another instead of the bodily proteins

Researchers for the first time have shown that members of a family of enzymes known as cathepsins - which are implicated in many disease processes - may attack one another instead of the bodily proteins they normally degrade. Dubbed "cathepsin cannibalism," the phenomenon may help explain problems with drugs that have been developed to inhibit the effects of these powerful proteases.

Protein folding: Nobel laureate Ahmed H. Zewail summarizes his insights

Living subjects are very complex systems and, at the same time, stunningly robust and accommodative. The secret of success are their proteins which build up the cells of the organisms, act as cleaners, messengers, transporter, motors, and fulfill much more jobs. How proteins are genetically coded and how their linear chains of amino acids are put together, is in principle well known.

Schizophrenia and the immune system: an interview with Prof Cyndi Shannon Weickert

Schizophrenia is the most disabling disease impacting youth today. It impacts 1% of the total population and typically causes withdrawal from society, loss in IQ, disordered thought and speech, hallucinations and delusions.

Latrepiridine reduces level of at least two neurodegeneration-related proteins in mice

The second of two studies on latrepirdine, recently published in Molecular Psychiatry, demonstrates new potential for the compound in the treatment of Alzheimer's disease, Parkinson's disease, sleep disorders, and other neurodegenerative conditions.

External stimulation impacts postnatal development of brain's white matter

A team at Children's National Medical Center has found that external stimulation has an impact on the postnatal development of a specific region of the brain. Published in Nature Neuroscience, the study used sensory deprivation to look at the growth and collection of NG2-expressing oligodendrocyte progenitor cells (NG2 cells) in the sensory cortex of the brain.

Antisense therapy shows promise in treating toxoplasmosis

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences.

Researchers identify key element in the development of Burkitt lymphoma

Burkitt lymphoma is a malignant, fast-growing tumor that originates from a subtype of white blood cells called B lymphocytes of the immune system and often affects internal organs and the central nervous system. Now Dr. Sandrine Sander and Professor Klaus Rajewsky of the Max Delbr-ck Center for Molecular Medicine (MDC) Berlin-Buch have identified a key element that transforms the immune cells into malignant lymphoma cells.

Targeting elevated HLX gene expression may treat acute myeloid leukemia

Scientists at Albert Einstein College of Medicine of Yeshiva University have made a discovery involving mice and humans that could mean that people with acute myeloid leukemia (AML), a rare and usually fatal cancer, are a step closer to new treatment options. Their study results were published online today in Cancer Cell.

Novel method identifies new oncogene that contributes to development of cancer

A team of researchers at Case Western Reserve University School of Medicine, led by Dr. Mark W. Jackson, have developed a novel method to identify genes that, when overexpressed, make normal cells behave like cancer cells.

Gadd45a protein plays a key role in skeletal muscle atrophy

Whether you're old, have been ill, or suffered an injury, you've watched gloomily as your muscles have atrophied. The deterioration of muscle-even slight or gradual-is about as common to the human condition as breathing.

New class of drugs may prove useful in treating cancer and aging-associated disorders

In a study published in the Proceedings of the National Academy of Sciences (PNAS) on Aug. 6, an international team led by Igor Roninson, of the University of South Carolina and the Medical University of South Carolina, reported the development of a new class of drugs that may prove useful in the treatment of cancer and aging-associated disorders.

Pathway describes how alpha hydroxyl acids cause skin exfoliation

A team of investigators from UC Davis and Peking University have discovered a mechanism that may explain how alpha hydroxyl acids (AHAs) -- the key ingredient in cosmetic chemical peels and wrinkle-reducing creams -- work to enhance skin appearance. An understanding of the underlying process may lead to better cosmetic formulations as well as have medical applications.
