Summary
Plasma cells (PCs), crucial for immunity via antibody secretion, also regulate hematopoiesis and neuro-inflammation. Their diverse functions beyond antibodies offer new immunotherapy potential.
Area of Science:
- Immunology
- Cell Biology
- Hematology
Background:
- Plasma cells (PCs) are terminally differentiated B lymphocytes.
- PCs are known for antibody (Ab) secretion and humoral immunity.
- Emerging evidence shows PCs influence processes beyond Ab production.
Purpose of the Study:
- To summarize current knowledge of PC biology.
- To focus on PC functions independent of Ab secretion.
- To discuss PC-based immunotherapy applications.
Main Methods:
- Literature review of recent studies on PC biology.
- Analysis of PC-environment interactions.
- Exploration of translational applications of PC immunotherapy.
Main Results:
- PCs regulate critical processes like hematopoiesis and neuro-inflammation.
- PC functionality is influenced by environmental signals.
- PCs possess a diverse functional repertoire beyond Ab production.
Conclusions:
- Plasma cells have multifaceted roles in health and disease.
- Understanding non-canonical PC functions is key for novel therapies.
- PC immunotherapy holds significant translational promise.

B Cell Activation and Differentiation
15.7K
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...

Cells of the Adaptive Immune Response
8.3K
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...

Antibody Actions
2.2K
Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.

Antibody Structure and Classes
8.0K
Antibodies, also known as immunoglobulins, are produced by B cells in response to foreign substances, such as bacteria and viruses. These proteins are critical for recognizing and neutralizing these substances, protecting the body from potential harm.
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
