Stand Up For Science Founder and CEO Colette Delawalla speaking at the Washington D.C. Take Back Our Science Rally!

Stand Up For Science Founder & CEO Colette Delawalla states three demands:

1. Remove RFK Jr.

2. Reinstate the American Dream of Science.

3. Science should be driven by scientists not political appointees.

Join the fight!

With this war on Iran costing $1B per day, we are now at 4$B, an amount that would fund 3,200 five year NIH biomedical research grants.

Letter from Sen. Fetterman dated March 6, 2026 telling me that he plans to vote for Elise Stefanik for UN Ambassador.

I wrote to my senators to urge them not to vote for Casey Means for surgeon general. Fetterman responded today (3/4/26), "I voted to confirm Senator Marco Rubio as Secretary of State and plan to do the same for Representative Elise Stefanik as U.S. Ambassador to the UN...." What? πŸ€¦β€β™€οΈ

JCI Insight - Antiretroviral treatment does not prevent extrapulmonary tuberculosis during SIV/Mtb coinfection in macaques

New paper in insight.jci.org by my & Ling Lin’s groups! TB is the most common infectious disease that causes death, causing >1 million deaths globally. HIV is the greatest risk factor for TB, causing worse clinical outcomes for both infections. We studied the effect of SIV infection 1/4

Does suppression of HIV replication protect against severe Mtb infection?

ASCI member Philana Ling Lin & team report on SIV/ART/TB models, finding antiretroviral treatment reduces pulmonary TB pathology, yet does not prevent extrapulmonary spread of TB: doi.org/10.1172/jci....

Stay tuned for our upcoming study where we show how SIV disrupts granuloma function, even during suppressive ART! 4/4

26.02.2026 14:29 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

The surprising extrapulmonary disease even after aggressive ART despite normalized CD4+ T cell counts & subtle changes in CD8+ T cell function underscore the need to understand the immunologic mechanisms of TB progression and how ART modulates immune responses impaired by HIV. 3/4

+/- antiretroviral therapy (ART) on Mtb infection. While very early suppressive ART prevented disease progression in lungs & lymph nodes, it did not inhibit dissemination of Mtb outside of the lung. Similarly, ART did not restore impaired T cell responses caused by SIV. 2/4

NOT-OD-26-020: Notice of Temporary Extension to Early-Stage Investigator (ESI) Eligibility Period NIH Funding Opportunities and Notices in the NIH Guide for Grants and Contracts: Notice of Temporary Extension to Early-Stage Investigator (ESI) Eligibility Period NOT-OD-26-020. OD

🧡Good news out of #NIH today.
(1) NIH is extending #ESI and #K99/R00 eligibility to accommodate researchers whose eligibility would have ended during the previous shutdown. Take a look at NOT-OD-26-020. If your ESI status would have ended in 2025, you get an automatic extension through 2026/03/31.
