SFB1328
Extracellular and intracellular adenine nucleotides (AN) impact on all central processes in biology and medicine. AN are essential and ubiquitous signaling molecules involved in regulating universal cellular processes, including (i) cell-cell communication and (ii) intracellular signaling.
Unresolved issues regarding the signaling function of extracellular AN in inflammation, e.g. adenosine triphosphate (ATP) or nicotinamide adenine dinucleotide (NAD), relate to the timing and location of their release, their conversion by ecto-enzymes, and their biological role within the balance of inflammatory processes. Likewise, the precise role of intracellular AN second messengers, e.g. nicotinic acid adenine dinucleotide phosphate (NAADP) or 3’,5’-cyclic adenosine monophosphate (cAMP), in the spatio-temporal control of signaling processes by forming or modulating microdomains with their metabolizing enzymes, specific binding proteins or receptors, or target ion channels remains largely unknown.
The central goal of the research consortium is to further our understanding of the regulatory roles of AN and their kinetics in the context of inflammatory diseases. Specific aims relate to (i) modulation of the balance between pro- and anti-inflammatory processes by AN converting ecto-nucleotidases and purinergic receptors, and to (ii) AN-driven intracellular calcium signaling and cAMP signaling in inflammation.
OBITUARY
The international scientific community has lost its pioneer in purinergic signalling! Geoffrey Burnstock died on the 2nd of June 2020 at the age of 91 in Melbourne (Australia). Our Collaborative Research Centre SFB1328 on adenine nucleotides in immunity and inflammation is unconceivable without Geoff Burnstock’s seminal work. Several times it has been a privilege to have Geoff Burnstock as plenary speaker during international meetings organised by members of the SFB1328.
RESEARCH TOPIC
Björn Rissiek and Andreas Guse, among others, are organising "The Versatile Role of Nicotinamide Adenine Dinucleotide in Immunity“ as a Research Topic for Frontiers Immunology. Submission deadline for abstracts is 30 June 2020.
