Wyzwania i Immune Cell Tracking

Immune cell trafficking in diabetes is complex. In type 1 diabetes, autoreactive T cells infiltrate trzustka islets, while innate imty cells like macrophages contribute to o emplomation in both type 1 and type 2 diabetes. To deflep effective therapie, research chers mutt visualize where these cells go, how long they stay, and whatthey do - all with a living organism.

Traditional methods such as flow cytometry and histologia provide snapshots but require tissue extraction, which ch destructs satigaal and d temporal context. Immunohistochestra can reveal cell type andd lokations in fixed sections, but it can not t capture dynamic movement or interactions. Moreover, these techniques are often limited to a single time point, missing thee evolving immage landscape that specizes diabetetes progression.

Thee result: a critial gap in understang how imme cells orchestrate β-cell destruction and, conversely, how regulatory cells might protect islets.
