Beyond commentary on Tfh subsets and GC biology, expect plenty of bread and baking-related content from this Bluesky page going forward - my sourdough starter is even older than my current year of MD/PhD training!
Lastly, please reach out if you have any ideas or questions regarding our preprint!

Using spatially resolved and multimodal single-cell analyses of human tonsil and blood, we unexpectedly converged upon GNG4 as a distinguishing feature of GC-localized Tfh. GNG4 encodes G protein subunit gamma 4, a modulator of GPCR signaling most known for its roles in neurons and cancer biology.
