Earlier this week, Seth Lederman, M.D., Chief Executive Officer of $TNXP, presented data on the Company's potential #mpox vaccine at the @UTSWMedCenter Symposium Microbiology Seminar Series, held in Dallas, Tex. The presentation, titled “Resurrecting Dr. Edward Jenner’s 1798 Horsepox Vaccine to Protect Against Mpox and Smallpox,” focused on recent TNX-801 findings that are consistent with mucosal immunity and suggest the ability to block forward transmission, similar to Dr. Edward Jenner’s vaccine, which eradicated smallpox and kept #mpox out of the human population.

Come be my colleague! I've been very, very happy at UTSW Micro. Supportive environment. Strong ambition. Strong empathy. Excellent resources. Check out Julie's thread for some statistics, financial incentives, and (bonus) grant-writing tips!
Faculty search announcement: Tenure-Track Assistant Professor in Microbiology at UT Southwestern. We seek candidates working in microbial pathogenesis (some preference may be given to bacterial pathogens). Come join our community! (1/5) jobs.utsouthwestern.edu/job/…

What I don't get about academia is the chronic lack of celebration. It is hard to get & maintain grant funding, hard to get papers accepted without Faustian bargains, hard to be a great mentor, & hard to maximize trainee success. All of it is hard. We should celebrate everything.

My review about “The HIV-1 transcriptional program” for the @JMolBiol special issue on transcription elongation is now out: doi.org/10.1016/j.jmb.2024.1…. I provide a 4 decades historical recount from mechanistic insights to implications for viral latency and cure. Thanks @NIAID!

Good luck to Don presenting at #ASV2024 on Tuesday, June 25 in the Poxvirus Workshop (W18-2)! He will be presenting work from our post-doc Dahee Seo in the @GammonLab on how poxvirus A51R proteins inhibit a cell-intrinsic immune response in macrophages!

Just finished a great meeting in Heidelberg on Innate Immunity in Host-Pathogen Interactions! Great job by @Aaron_Embry_ on presenting our work on how bacterial effectors can break virus restriction! #EESImmunity
