Tertiary lymphoid tissue
Tumor-infiltrating lymphocytes influence colorectal cancer progression. We have recently documented that tertiary lymphoid tissue in the colorectal cancer microenvironment orchestrates lymphocyte infiltration and that tertiary lymphoid tissue and lymphocytes cooperate in a coordinated antitumor immune response to improve patient outcome. Thus, tertiary lymphoid tissue represents a potential tar...
متن کاملTertiary Intratumor Lymphoid Tissue in Colo-Rectal Cancer
Ectopic (or tertiary) lymphoid tissue develops at sites of inflammation or infection in non lymphoid organs and is associated with chronic inflammation. In colon mucosa, small lymphoid aggregates are already present in homeostatic conditions, as part of the gut-associated lymphoid tissue and play an essential role in the immune response to perturbations of the mucosal microenvironment. Despite ...
متن کاملHelicobacter-induced chronic active lymphoid aggregates have characteristics of tertiary lymphoid tissue.
Susceptible strains of mice that are naturally or experimentally infected with murine intestinal helicobacter species develop hepatic inflammatory lesions that have previously been described as chronic active hepatitis. The inflammatory infiltrates in some models of chronic autoimmunity or inflammation resemble tertiary lymphoid organs hypothesized to arise by a process termed lymphoid organ ne...
متن کاملLymphoid Neogenesis and Tertiary Lymphoid Organs in Transplanted Organs
The progressive organization of immune effectors into functional ectopic lymphoid structures, named tertiary lymphoid organs (TLO), has been observed in many conditions in which target antigens fail to be eliminated by the immune system. Not surprisingly, TLO have been recurrently identified in chronically rejected allografts. Although significant progress has been made over the last decades in...
متن کاملTertiary Lymphoid Organs in Takayasu Arteritis
OBJECTIVE The role of B cells in the pathogenesis of Takayasu arteritis (TA) is controversial. We aimed to study the presence of tertiary lymphoid organs (TLOs) in the aortic wall of TA patients. METHODS Hematoxylin and eosin-stained sections from aorta specimens from patients with TA were screened for TLOs. The presence of B cell aggregates (CD20), follicular dendritic cells (FDCs, CD21), an...
