Kupffer cell

Encyclopedia : K : KU : KUP : Kupffer cell


Kupffer cells or Browicz-Kupffer cells are specialized macrophages located in the liver that form part of the reticuloendothelial system. The cells were first observed by Johannes von Kupffer in 1876. The scientist called them "sternzellen" (star cells or stellate cells) but thought falsely that they were an integral part of the endothelium of the liver blood vessels and that they originated from it. In 1898, after several years of research, Tadeusz Browicz identified them correctly as macrophages.

Their development begins in the bone marrow with the genesis of promonocytes and monoblasts into monocytes and then on to peripheral blood monocytes completing their differentiation into Kupffer cells.

Helmy et al. identified a receptor present in Kupffer cells, the complement receptor of the immunoglobulin family (CRIg). Mice without CRIg could not clear complement system-coated pathogens. CRIg is conserved in mice and humans and is a critical component of the innate immune system - Cell 124, 915 (2006).

As a result of steady state population dynamics or inflammation it is suggested that M-CSF (Monocyte-colony stimulation factor) is the cytokine responsible for its differentiation (Naito et al 1997).
