Beginning of modern concept of inflammation: the work of Friedrich Daniel von Recklinghausen and Julius Friedrich Cohnheim

August Heidland et al. J Nephrol. 2009 Nov-Dec.

Abstract

In Rudolf Virchow's concept of inflammation, the basic alterations were derived from connective tissue cells, which underwent a marked metamorphosis. This cell-based and static conception was fundamentally broadened and, in part, refuted in the ensuing decade by 2 of his scholars. Friedrich Daniel von Recklinghausen characterized the pus cells in acute inflammation and made the seminal observation of their contractility and mobility. He was the first who described the wandering leukocytes which were demonstrated in particular in experimental keratitis. He also showed that pus cells could migrate from the places of their origin in the interstitium to other tissues and epithelial cells. Von Recklinghausen in addition contributed to the concept of phagocytosis. The work of Julius Friedrich Cohnheim was focused on the mechanisms involved in the extravasation of leukocytes from the blood vessels in the inflamed mesentery of the frog and carefully described the time-dependent alterations: dilatation of the arteries and veins, adhesion of colorless cells to the endothelial cells, and the subsequent transmigration from the capillaries and venules into the interstitial space. In the last few decades, experimental and clinical studies using modern techniques have fully confirmed and extended these basic observations made by von Recklinghausen and Cohnheim more than 100 years ago.
