What did Paul Langerhans discover?

insulin
Paul Langerhans (25 July 1847 – 20 July 1888) was a German pathologist, physiologist and biologist, credited with the discovery of the cells that secrete insulin, named after him as the islets of Langerhans.

Who discovered Langerhan cells?

Paul Langerhans
Langerhans cells are named after Paul Langerhans, a German physician and anatomist, who discovered the cells at the age of 21 while he was a medical student.

What are the islets of Langerhans?

Islets of Langerhans are islands of endocrine cells scattered throughout the pancreas. A number of new studies have pointed to the potential for conversion of non-β islet cells in to insulin-producing β-cells to replenish β-cell mass as a means to treat diabetes.

What is islets of Langerhans in biology?

islets of Langerhans, also called islands of Langerhans, irregularly shaped patches of endocrine tissue located within the pancreas of most vertebrates. They are named for the German physician Paul Langerhans, who first described them in 1869. The normal human pancreas contains about 1 million islets.

What layer of the skin are Langerhans cells found?

Langerhans cells (LCs) reside in the epidermis as a dense network of immune system sentinels. These cells determine the appropriate adaptive immune response (inflammation or tolerance) by interpreting the microenvironmental context in which they encounter foreign substances.

What is Langerhans Cell Histiocytosis?

Langerhans cell histiocytosis is a rare disorder that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a rare disease that begins in LCH cells. LCH cells are a type of dendritic cell that normally helps the body fight infection.

What is the function of Langerhan cells?

Are Langerhan cells antigen presenting cells?

Langerhans cells (LC) are members of the dendritic cells family, residing in the basal and suprabasal layers of the epidermis and in the epithelia of the respiratory, digestive and urogenital tracts. They specialize in antigen presentation and belong to the skin immune system (SIS).

What is the function of pancreatic islets?

The pancreatic islets are small islands of cells that produce hormones that regulate blood glucose levels. Hormones produced in the pancreatic islets are secreted directly into the blood flow by five different types of cells.

What is the function of islets of Langerhans cells?

The islets of Langerhans are a cluster of cells within the pancreas that are responsible for the production and release of hormones that regulate glucose levels.

What do the islets of Langerhans produce?

There are five types of cells in the islets of Langerhans: beta cells secrete insulin; alpha cells secrete glucagon; PP cells secrete pancreatic polypeptide; delta cells secrete somatostatin; and epsilon cells secrete ghrelin.
