Delighted & proud that this wonderful collection in @jem.org includes our study characterising dominant negative variants in ITPR3 in syndromic combined immunodeficiency patients due to calcium channel leakiness of the IP3 receptor, causing ER Ca2+ store depletion and impaired Ca2+ T cell dynamics.
Check out our new collection on lymphocyte cell differentiation in specific microenvironments and innate immune memory, accompanying the upcoming @keystonesymposia.bsky.social joint meetings on these topics 👉 https://buff.ly/3CgbKL7

Very grateful to have been introduced to the wonderful #IBEX Knowledge-Base community 👇🏾 and to this novel spatial proteomics technique. Looking forward to more multiplexed imaging!
Multiplexed imaging is a powerful approach in spatial biology, but is complex, expensive & labor-intensive. This Community Page presents the IBEX Knowledge-Base, a central resource for reagents, protocols & more, to enhance knowledge sharing & innovation of multiplexing techniques.🧪

Our thymus, a critical source and trainer of T cells, involutes with aging. 2 new studies find a growth factor (FGF21) that delays involution (in mouse models) and may be a way to rejuvenate our immune system and promote healthy aging in the future.

Auschwitz was at the end of a long process. It did not start from gas chambers.

This hatred was gradually developed by humans. From ideas, words, stereotypes & prejudice through legal exclusion, dehumanization & escalating violence... to systematic and industrial murder.

Auschwitz took time.
