Summary
Sjögren's syndrome (SS) is an autoimmune disease affecting glands. Research shows B-cells play a key role in SS pathogenesis, making B-cell targeted therapies effective.
Area of Science:
- Immunology
- Autoimmunity
- Epithelial Biology
Background:
- Sjögren's syndrome (SS) is an autoimmune epithelitis characterized by epithelial cell disruption and lymphocytic infiltration of lacrimal and salivary glands, leading to dryness.
- The etiology of SS is multifactorial, involving genetic and environmental factors, with potential modulation by viruses and sex hormones.
Purpose of the Study:
- To review the compelling evidence implicating B-cells in the pathophysiology of Sjögren's syndrome.
- To highlight the shift in understanding from T-cell centric to B-cell centric roles in SS pathogenesis.
Main Methods:
- Literature review of studies investigating lymphocyte involvement in Sjögren's syndrome.
- Analysis of recent findings on B-cell functions and their relevance to SS.
Main Results:
- While T-cells have been historically emphasized, recent evidence highlights the significant role of B-cells in SS.
- Elevated levels of B-cell activating factor (BAFF) contribute to B-cell abnormalities in SS, including the development of self-reactive B-cells.
Conclusions:
- Sjögren's syndrome serves as a model for B-cell-mediated autoimmunity.
- B-cell-ablative treatments have demonstrated considerable efficacy in managing SS, supporting the central role of B-cells.

Secondary Lymphoid Organs
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
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...

Lymphoid 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...

Primary Lymphoid Organs
Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Cells of the Adaptive Immune Response
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
B 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...
