His prime research activities focus on mechanisms of protective immunity towards pathogens.[1] From 1970-80 he analysed T-T Cell interactions during the induction of cytotoxic T Cell responses.[2] During his Ulm period he focussed on the immunobiology of bacterial superantigens.[3] In Munich, he subsequently contributed to our understanding of Toll-like-Receptors(TLR), through which innate immune cells sense pathogens. In particular he was one of the first to realise[4] that bacterial/viral DNA activated Innate Immune cells via TLR9.[citation needed] Conversely his group was able to show that TLR7 and/or TLR8 recognised pathogen-derived RNA[5][6] while TLR13 senses bacterial 23S rRNA.[7]
