Abstract:
It is often argued that T cell-mediated immunity to secondary infection is dependent on the 'accelerated' responses of memory T cells in lymph nodes. However, new evidence points to a crucial role for effector memory T cells, which are resident in peripheral tissues, in immune protection. These T cells, which reside in peripheral tissues, are not necessarily bound by an anatomical structure and can be present at many sites. Collectively, they represent a third functional tissue of the immune system, uniquely specialized to mediate protective immunity. We propose that the paradigm 'effector lymphoid tissue' needs to be articulated and developed as a focus of new research to describe and understand the unique role this tissue has in protective immunity.

Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Functions of the Lymphatic and Immune System
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
