Lymph Node Cross-Section
Within the human body, there are many lymph nodes – specialized organs that trigger immune responses – that are connected to individual organs by lymph vessels to remain informed about bodily infections. From the organs, the lymph vessels transport fluids and dendritic cells (immune cells that pass information onto other immune cells) to the lymph nodes.
This image was taken in relation to a study into how, alongside dendritic cells, so-called unconventional T cells also continuously migrate from the tissue into the lymph nodes and influence the immune responses there.
The image shows a cross-section through a lymph node. The unconventional T cells (green), which have migrated from the tissue via the lymphatic channels, are located in the marginal sinus and in the interfollicular zone. Follicular B cells are shown in magenta, the lymph node capsule and lymphatic vessels in blue.
