The book "Cell Communication in Nervous and Immune System" offers a comprehensive analysis of the communication mechanisms between the nervous system and the immune system. Although these two systems may seem very different at first glance, they exhibit remarkable parallels in the way they process and store information. The authors, renowned experts in the fields of immunology as well as molecular and cellular neurobiology, present a collection of overviews that juxtapose the cellular communication means and signaling mechanisms of both systems. This work highlights the interactions between the two systems and their significance, which has only recently been fully appreciated. The discussion of the shared synaptic structures and the associated proteins provides valuable insights into the functioning of these complex biological systems.
