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.
5th German Pharm-Tox Summit
At the 5th German Pharm-Tox Summit the annual meeting of the German Society for Experimental and Clinical Pharmacology and Toxicology (DGPT) a whole Symposium was dedicated to the SFB1328.
EVENT
With 90 attendee's and 5 invited Speakers, the "Life after PhD meeting" was a great success!
Special thanks to the PhD students for organising the meeting and to the invited speakers for their open talks and discussions!
