Research Articles


PARKINSON’S DISEASE
The trophic response of dopamine neurons to GDNF, mediated by the transcription factor Nurr1, protects them from α-synuclein–mediated toxicity.

NEURODEGENERATIVE DISEASE
Ube3a deficiency causes a decrease in cerebellar tonic inhibition by preventing degradation of GABA transporter 1 in a mouse model of Angelman syndrome.

IMMUNOLOGY
Duplication of the MECP2 gene in humans and mice results in immune dysregulation due in part to the suppression of IFN-γ production from T helper cells.


Focus


IMMUNE DYSFUNCTION
Modest overexpression of an epigenetic regulatory protein alters T helper cell differentiation and immune defects.

REGULATORY SCIENCE
FDA announces a partnership—the Medical Device Innovation Consortium—to advance regulatory science in the medical technology arena.


Editors' Choice


IMMUNOLOGY
Noncanonical major histocompatibility complex class I may contribute to natural killer cell licensing.

ALLERGY
A new strategy for stripping immunoglobulin E from mast cells has potential as a therapy for anaphylaxis-inducing allergic reactions.

STEM CELLS
Signaling through the Toll-like receptor TLR3 is necessary for generation of induced pluripotent stem cells

AUTOIMMUNITY
The same signals that initiate B cell–T cell interactions may be responsible for regulatory B cell differentiation.

DIABETES
Coffee and tea intake is associated with a lower risk of type 2 diabetes.

ASTHMA
Obesity hinders the clearance of dead inflammatory cells in asthmatic lungs and is associated with reduced glucocorticoid responsiveness and oxidative stress.
