Langhans cells

Langhans cells are microscopic structures that form in tissues during certain diseases. They were described by the German pathologist Theodor Langhans in the 1870s.

Langhans cells are clusters of macrophages, cells that play an important role in protecting the body from infections and other pathogens. In some diseases, such as tuberculosis or syphilis, macrophages can become activated and begin to produce large amounts of cytokines, leading to the formation of Langhans cells.

The presence of Langhans cells can be a diagnostic sign of these diseases. In addition, Langhans cells can be used to study the mechanisms of the immune response and inflammation processes.

However, despite their diagnostic value, Langhans cells are not specific for specific diseases. They can also form in other conditions, such as autoimmune diseases or infections with other pathogens.

Thus, Langhans cells play an important role in the diagnosis and study of pathological processes in the body, but they are not the only marker of the disease.

Langgans, Hungarian pathologist and embryologist, doctor of medicine, professor (1838-1916). Received medical education in Budapest; was an assistant to I. Pfeiffer, one of the founders of the comparative-historical direction in embryology and famous for his research in the field of comparative anatomy. In 1867 he was elected secretary of the Hungarian Union of Naturalists; was engaged in teaching and literary criticism. From January 1906 he headed the newly opened Department of Histology at the University of Vienna.

Langhans is credited with creating the so-called Löwenstern chorioallantoid tests or umbilical cord test, which is widely used in modern science to this day. A number of interesting observations given to him relate to the human embryo and other vertebrates, allowing him to formulate the conclusion
