Apr 23, 2007·Tertiary lymphoid tissues are lymph node‐like cell aggregates that arise at sites of chronic inflammation. They have been observed in transplanted organs undergoing chronic rejection, but it is not known whether they contribute to the rejection process by supporting local activation of naïve lymphocytes.

Tertiary Lymphoid Organs (TLOs): powerhouses of disease ...

A central tenet of immunity is that primary immune responses are carried out in secondary lymphoid organs (SLOs) such as lymph nodes, spleen, and Peyer´s patches. However, in view of the recent characterization of tertiary lymphoid organs (TLOs) in clinically important diseases, this paradigm calls for re-examination. Unlike SLOs, TLOs arise in response to nonresolving diseases at ...
