Expanded T cells from pancreatic lymph nodes of type 1 diabetic subjects recognize an insulin epitope

Article Abstract:

The T cells from pancreatic draining lymph nodes, the site of islet-cell-specific self-antigen presentation, are examined. The results identify insulin-reactive, clonally expanded T cells from the site of autoinflammatory drainage in long-term type 1 diabetics, indicating that insulin may indeed be the target antigen causing autoimmune diabetes.

Subcapsular sinus macrophages in lymph nodes clear lymph-borne viruses and present them to antiviral B cells

Article Abstract:

The presence and importance of macrophages on the floor of subcapsular sinus (SCS) and in the medulla of lymph nodes in clearing lymph-borne viruses are demonstrated. These macrophages are found to be extremely useful in initiating humoral immune responses.

T-cell priming by dendritic cells in lymph nodes occurs in three distinct phases

Article Abstract:

The phenotype of injected dendritic cells (DCs) that migrated to draining lymph nodes (LNs) is examined. Primary T-cell responses in LNs require contactdependent information exchange between T cells and DCs.
