Natural killer T cells play important role in Lyme disease

A research team led by the La Jolla Institute for Allergy & Immunology and Albany Medical College has illuminated the important role of natural killer (NK) T cells in Lyme disease, demonstrating that the once little understood white blood cells are central to clearing the bacterial infection and reducing the intensity and duration of arthritis associated with Lyme disease.

Multitasking proteins driving cell behavior

A study describing how cells within blood vessel walls move en masse overturns an assumption common in the age of genomics - that the proteins driving cell behavior are doing so much multitasking that it would be near impossible to group them according to a few discrete functions.

Scientists develop 'barcode chip' to revolutionize diagnostic medical testing

In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease.

Tissue analyses indicate survival benefits for some lung cancer patients

Taking small tissue samples from patients with lung cancer and examining them under a microscope (a procedure called histology) is now being utilized to better tailor the chemotherapy treatments to improve survival in some patients with non-small cell lung cancer, according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, cosponsored by ASTRO, ASCO, IASLC and the University of Chicago.

H5N1 protein hides in tiny tubules

A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response from infected cells, said Baylor College of Medicine researchers in an online report in the journal Nature.

How the Nodal gene family keeps the heart in the right (asymmetric) place

Asymmetry is crucial for the heart proper functioning, and now, scientists from the Institute Gulbenkian of Science in Portugal and Harvard University, have discovered that a family of genes, called Nodal, is crucial determining this asymmetry by controlling the speed and direction of the heart muscle cells during embryonic development.
