Regulation of antiviral responses by RIG-I dissociation from dsRNA

Im, Jung Hyun 京都大学 DOI:10.14989/doctor.k24984

2023.11.24

概要

1.1 RLRs
The innate immune system is systemized to react against viral infections as the
first-defence mechanism of host together with the adaptive immune system. Several
cytoplasmic sensor proteins detect viral RNA and elicit antiviral signals upon viral
invasion. RIG-I-like receptors (RLRs) are the most front-line viral RNA sensing
proteins in cytoplasm and ubiquitously expressed in almost every type of cells1.
Therefore, many cases have been reported that deficiency of RLRs caused severe
immune disorders2,3. RLRs-knockout mice lost the function of detecting viral RNAs in
fibroblast, and conventional dendritic cells (cDC). ...

Thanks to all Fujita lab members, I could complete my research.

Specially thanks to Professor Fujita. He introduced RIG-I protein and guided me to

innate immune field. Thanks to his massive knowledges and experiment technique, I

was able to try lots of interesting experiments. Especially, his attitude towards

research always inspires me not to lose my own way.

Also, thanks to Professor Shige H. Yoshimura, allowed me to use AFM machine.

I appreciate to Ivana for helping me to plan RIG-I experiments and teaching

experiments including AFM, protein purification, Seong-Wook Oh for advice and

support, and Koshiba-san, who is working for lab as secretary, for many helps.

I appreciate to Prof. Noda and three referees for great helps for reviewing my thesis. I

could study how to present scientific results correctly and how to make precise

statistical analysis.
