HDAC4 is required for inflammation-associated thermal hypersensitivity

HDAC4 is required for inflammation-associated thermal hypersensitivity

Transcriptional alterations are characteristic of persistent pain states, but the key regulators remain elusive. HDAC4 is a transcriptional corepressor that has been linked to synaptic plasticity and neuronal excitability, mechanisms that may be involved in peripheral and central sensitization. Using a conditional knockout (cKO) strategy in mice, we sought to determine whether the loss of HDAC4...

Eating disorder predisposition is associated with ESRRA and HDAC4 mutations.

Anorexia nervosa and bulimia nervosa are common and severe eating disorders (EDs) of unknown etiology. Although genetic factors have been implicated in the psychopathology of EDs, a clear biological pathway has not been delineated. DNA from two large families affected by EDs was collected, and mutations segregating with illness were identified by whole-genome sequencing following linkage mappin...

Autophagy Is Required for Neutrophil-Mediated Inflammation.

Autophagy, an intracellular degradation and energy recycling mechanism, is emerging as an important regulator of immune responses. However, the role of autophagy in regulating neutrophil functions is not known. We investigated neutrophil biology using myeloid-specific autophagy-deficient mice and found that autophagy deficiency reduced neutrophil degranulation in vitro and in vivo. Mice with au...

Hypersensitivity Is Mediated by Early Skin Inflammation During Contact

Lymphangiogenesis Is Required for Pancreatic Islet Inflammation and Diabetes

Lymphangiogenesis is a common phenomenon observed during inflammation and engraftment of transplants, but its precise role in the immune response and underlying mechanisms of regulation remain poorly defined. Here we showed that in response to injury and autoimmunity, lymphangiogenesis occurred around islets and played a key role in the islet inflammation in mice. Vascular endothelial growth fa...
