BDNF and myeloid sarcoma: In addition to neuron cells, BDNF is also reported to be expressed in immune cells such as B and T cells as well as macrophages (Kerschensteiner et al. 1999; Kruse et al. 2007) and is particularly detected in inflammatory responses within the central nervous system (CNS), such as those associated with conditions like MS (Stadelmann et al. 2002).
