7/29. Jeongmin spoke about "Targeting drug-resistant infections" as part of the K-BioX Global Mentoring Program to encourage bright next-gen scientists to join the infectious disease research community and tackle the global threat together!

7/29. We celebrated our recent paper accepted by Cell Reports! Congrats to all co-authors, including Dr. Nicholas Mantis's group at New York State Department of Health and Dr. Chris Fromme's group here at Cornell!!! This paper explains a 3D structure associated intrinsic mechanism affecting neutralizing efficacies of antibodies. We used typhoid toxin and javiana toxin as examples. We applied the experimental findings to other asymmetrical AB5 toxins (E. coli PltAB toxin, cholera toxin, Shiga toxin, pertussis toxin), highlighting new features in the toxin-antibody interactions and offering important insights into anti-toxin strategies. We are very proud of this work! Please check it out when the final version becomes available.

7/26. Our research article entitled "The structural basis of Salmonella A2B5 toxin neutralization by antibodies targeting the glycan-receptor binding subunits" is accepted by Cell Reports!!! Available at SSRN: http://dx.doi.org/10.2139/ssrn.3745287

7/14. Our recent review article "Glycan-Mediated Molecular Interactions in Bacterial Pathogenesis" is now available online in Trends in Microbiology. Feel free to share it with your network! https://authors.elsevier.com/a/1dPIO,L%7EyCfUxU. Also, feel free to share your feedback with us!

7/7-8. Jeongmin joined one of the NIH study sections evaluating graduate student and postdoc training grants (F30, F31, and F32). Obtained many useful information about mentoring next-gen scientists. Ready to implement them!
