Some of which then serve as antigenic epitopes for T lymphocytes. Afferent lymphatic channels Also simply called lymphatics. afferent lymphatic channels are veinlike structures that drain extracellular fluid (ie. lymph) from a site into a regional node. Lymphatics serve 2 major purposes: to convey immune cells and to carry whole antigen from the site of inoculation to a lymph node. Antigen-presenting cells APCs are specialized cells that bind and phagocytize antigen at a site. Following ingestion of antigen.

Principles and Practice of Ophthalmology. 2nd ed. Philadelphia, PA: WB Saunders; 2000:74-82. Lymphocyte-Mediated Effector Responses Oelayed hypersensitivity T lymphocytes Delayed hypersensitivity (Coombs and Gell type IV) represents the prototypical adaptive immune mechanism for lymphocyte-triggered inflammation. It is especially powerful in secondary immune responses. Previously primed DH CD4 T lymphocytes leave the lymph node, home into local tissues where antigen persists, and become activated by further restimulation with the specific priming antigen and MHC class II - expressing CLINICAL EXAMPLE 2·2 Identification of rubella virus reactivity in Fuchs heterochromic iridocyclitis Fuchs heterochromic iridocyclitis (FHI) is a unilateral chronic anterior uveitis that frequently features elevated intraocular pressure, early cata ract, and iris atrophy leading to heterochromia.

T regulatory (Treg) cells form another subset of helper T cells; they are identified not by their cytokine profile but by the simulta neous surface expression ofCD4, CD2S, and Foxp3. Treg cells are essentiall y suppressor-type T cells that down -regulate other T cell populations. Treg cells appear to be generated in the thymus in d evelop me nt and are essential to self-tole rance, the process by which auto reactive T cells are minimized and their function down- regulated. These subsets are important because the different cytokines produced by different cell typ es profoundly influence subsequent "downstream" immune processing, B-Iymp hocyte CHAPTER 2: Immunization and Adaptive Immunity.
