Journal of Indian Society of Periodontology, 2011 Langerhans cell histiocytosis (LCH) is a group of rare disorders histologically characterized by the proliferation of Langerhans cells. Multiple organs and systems may be involved by the disease. Typically, there is bone involvement and, less frequently, lesions may be found in the lungs, liver, lymph nodes, skin, and mucosa.

Pulmonary Langerhans cell histiocytosis causing spontaneous bilateral pneumothorax in a child
The Egyptian Journal of Internal Medicine, 2015 Bilateral pneumothorax is very rare in childhood. Moreover, if it is due to pulmonary involvement of Langerhans cell histiocytosis, it is even rarer in childhood.

Shaping bursting by electrical coupling and noise [PDF]
Biological Cybernetics Volume 106, Number 2 (2012), 67-88, 2011 Gap-junctional coupling is an important way of communication between neurons and other excitable cells. Strong electrical coupling synchronizes activity across cell ensembles. Surprisingly, in the presence of noise synchronous oscillations generated by an electrically coupled network may differ qualitatively from the oscillations produced by uncoupled ...

Learning theories reveal loss of pancreatic electrical connectivity in diabetes as an adaptive response [PDF]
PLoS ONE 8(8): e70366 (2013), 2013 Cells of almost all solid tissues are connected with gap junctions which permit the direct transfer of ions and small molecules, integral to regulating coordinated function in the tissue. The pancreatic islets of Langerhans are responsible for secreting the hormone insulin in response to glucose stimulation.

The effects of beta-cell mass and function, intercellular coupling, and islet synchrony on $\textrm{Ca}^{2+}$ dynamics [PDF]
, 2020 Type 2 diabetes (T2D) is a challenging metabolic disorder characterized by a substantial loss of $\beta$-cell mass and alteration of $\beta$-cell function in the islets of Langerhans, disrupting insulin secretion and glucose homeostasis. The mechanisms for deficiency in $\beta$-cell mass and function during the hyperglycemia development and T2D ...
