Summary
Follicular dendritic cells (FDC) exhibit distinct ultrastructural features and functions within lymphoid follicles (LF). Their roles in B cell development and disease pathogenesis are crucial, with origins potentially from fibroblastic reticulum cells.
Area of Science:
- Immunology
- Cell Biology
- Histology
Background:
- Lymphoid follicles (LF) are key sites for adaptive immune responses.
- Dendritic cells, particularly follicular dendritic cells (FDC), play critical roles in LF structure and function.
- Understanding FDC morphology and function in health and disease is essential for immunology.
Purpose of the Study:
- To review the ultrastructural morphology and functions of FDC in reactive lymphoid follicles.
- To elucidate the pathognomonic role of FDC in specific disease conditions.
- To explore the cellular origin of FDC.
Main Methods:
- Review of existing literature on FDC ultrastructure and function.
- Analysis of FDC characteristics in different zones of reactive lymphoid follicles.
- Examination of FDC roles in autoimmune and immunosuppressive disorders.
Main Results:
- FDC display distinct ultrastructural features across five follicular zones, correlating with zone-specific functions.
- FDC express cytokine receptors but primarily produce TGF-beta.
- FDC are implicated in B cell proliferation and selection, with altered function in autoimmune (hyperfunctional) and immunosuppressive (dysfunctional) diseases.
- FDC likely originate from fibroblastic reticulum cells.
Conclusions:
- FDC possess unique ultrastructural and functional properties that vary by follicular zone.
- FDC play a vital role in B cell dynamics, including migration, proliferation, selection, and differentiation within secondary lymphoid follicles.
- FDC dysfunction or hyperfunction is associated with specific immune and autoimmune diseases.

01:06Multipotency and Niche of Bulge Stem Cell
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...
01:18Lymphoid Cells and Tissues
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
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...

01:23Detailed Structure and Function of Lymph Nodes
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

01:22Antigen Presenting Cells
The immune system is a complex network of cells and molecules that protects the body from foreign invaders. T cells, a type of white blood cell, play a crucial role in this process. They recognize and attack foreign substances, such as pathogens, that enter the body.
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...

01:24B Cell Activation and Differentiation
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

01:27Histology of the Small Intestine
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...
