Hank Seifert is a Professor at Northwestern Medical School in Chicago. I'm interested in everything, particularly bacteria, but our group studies the Neisseria gonorrhoeae pilus—antigenic variation and functions.

The NIH ordered me to stop my ‘dangerous’ gain-of-function research. It isn’t dangerous at all Safe gain-of-function research is necessary to identify new treatments for diseases like for tuberculosis — but the NIH has imposed unfounded stops.

Our latest efforts to understand Enterococcal wound infection. In long-term collaboration with @gthibault.bsky.social, we discovered how E. faecalis makes extracellular ROS - via EET!⚡️Which in turn dysregulates host UPR to delay wound healing. Led by @aarontan.bsky.social - his videos below are 🤩!

Expansion of tetM-Carrying Neisseria gonorrhoeae in the United States, 2018–2024 | NEJM During 2018–2024, the percentage of N. gonorrhoeae isolates carrying tetM, which confers tetracycline resistance, increased from less than 10% to more than 30% across the United States.

New @nejm.org report shows a rapid rise in tetM-carrying Neisseria gonorrhoeae strains in the U.S. jumping from <10% in 2020 to >30% by early 2024.
Why? Likely linked to our increased use of doxycycline both for STI treatment and DoxyPEP.

Two line graphs show NIH Outlays for Grants at Brown University. The left graph, "Outlay per month (USD)," shows monthly outlays from October (P01-P02) to June (P09) for fiscal years 2022, 2023, 2024, and 2025. The 2025 line (black) shows outlays around $15,000,000 from October 2024 to March 2025, then drops sharply to $0 in April 2025 and remains at $0 for May and June. Lines for previous fiscal years remain above $10,000,000 throughout the period. The right graph, "Percent of grants without an outlay," shows the percentage of grants without monthly outlays over the same period. The 2025 line (black) shows percentages below 10% until March 2025, then spikes to 100% in April 2025 and remains at 100% for May and June. Lines for previous fiscal years remain below 20%.

This is more than just lost grant dollars...this is patients in experimental treatments for incurable cancers having to stop their course of treatment.

It's patients with medical devices going unmonitored.

It's entire lines of groundbreaking science coming to a hard stop.
