Cell receptor has proclivity for T helper 9 cells, airway inflammation

Posted: 29 Jul 2012 11:22 AM PDT

A cell surface molecule, OX40, is a powerful inducer of T helper cells that make copious amounts of interleukin-9. Such TH9 cells are responsible for ongoing inflammation in the airways in the lungs in vivo.

Gene discovery set to help with mysterious paralysis of childhood

Posted: 29 Jul 2012 11:22 AM PDT

Alternating hemiplegia of childhood is a very rare disorder that causes paralysis that freezes one side of the body and then the other in devastating bouts that arise at unpredictable intervals. Seizures, learning disabilities and difficulty walking are common among patients with this diagnosis. Researchers have now discovered that mutations in one gene cause the disease in the majority of patients with a diagnosis of AHC, and because of the root problem they discovered, a treatment may become possible.

Elusive gene that causes a form of blindness from birth dlscovered

Posted: 29 Jul 2012 11:21 AM PDT

Researchers have isolated an elusive human gene that causes a common form of Leber congenital amaurosis (LCA), a relatively rare but devastating form of early-onset blindness. The new LCA gene is called NMNAT1. Finding the specific gene mutated in patients with LCA is the first step towards developing sight-saving gene therapy.

Bone tissue engineering: Attaching proteins for better regeneration

Posted: 29 Jul 2012 11:21 AM PDT

Researchers have demonstrated a new protein binding approach for effectively promoting bone regeneration. Current treatments for bone defects and bone tissue regeneration have significant limitations. Now a new method that immobilizes a fusion protein in a hybrid collagen-polymer supportive scaffold shows promise for bone tissue engineering.
