Recombinant Human Neuregulin1‐β1 Significantly Reduces Schwannoma Growth in Mice
Annals of Neurology, EarlyView.rhNRGβ1‐Replacement‐Therapy: Under physiological conditions, NRGβ1 is expressed on axons (in orange), where it activates ERBB2 receptors, facilitating successful nerve regeneration following injury. However, loss of NF2 leads to a reduction in NRGβ1‐expression and increased ErbB2 levels on Schwann cells (in green), which contributes to schwannoma ...

The Korean Journal of Thoracic and Cardiovascular Surgery, 2014 We present a case of a 55-year-old woman who complained of chest pain at rest. A mass was detected adjacent to her left atrium. The mass was completely excised, and a pathologic examination revealed it to be a schwannoma. Schwannomas are tumors that originate in the nerve sheath and are rarely detected in the heart.

The Anatomical Record, EarlyView.Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Cystic schwannoma mimicking a second branchial cleft cyst on computed tomography
Medical Journal of Dr. D.Y. Patil University, 2015 Schwannoma of the neck is a relatively uncommon tumor. Schwannoma present as insidious, slow-growing, painless masses, characteristics that often lead to an incorrect diagnosis. Cystic schanommas among schanommas are a rare entity.
