• Germinal centers in B-cell follicles are sites where B cells undergo intense proliferation after encountering specific antigens and cooperating T cells.
• The adaptive immune system is comprised of two types of lymphocytes: B cells and T cells.
• IL-4 is classified as an adaptive immunity cytokine, is produced by Th cells, binds to the CD124 receptor, targets B cells, T cells, and macrophages, and functions in the proliferation of B and cytotoxic T cells, enhancement of MHC class II expression, and stimulation of IgG and IgE production.
• Germinal centers within B-cell follicles are sites where B cells undergo intense proliferation after encountering their specific antigen and cooperating T cells.
• IL-6 is produced by monocytes, fibroblasts, and endothelial cells, and upon stimulation, it is secreted by macrophages, T cells, B cells, mast cells, glial cells, eosinophils, keratinocytes, and granulocytes.
• Primary immunodeficiencies result from a defect in one or more elements or functions of the normal immune system, such as T cells, B cells, NK cells, neutrophils, monocytes, antibodies, cytokines, or the complement system.
• IL-2 is classified as an adaptive immunity cytokine, is produced by Th1 cells, binds to the CD25 receptor, targets activated T cells, B cells, and NK cells, and functions in the proliferation of B cells and activated T cells, and supports NK cell function.
• T lymphocytes (T cells) consist of two main classes: cytotoxic T cells, which kill virus-infected cells, and a second class that activates other cells such as B cells and macrophages.
• IL-10 is classified as an anti-inflammatory cytokine, is produced by T cells, B cells, and macrophages, binds to the CDw210 receptor, targets B cells and macrophages, and functions to inhibit cytokine production and mononuclear cell function.
• The most common cells of the immune system are lymphocytes (T cells, B cells, and NK cells), neutrophils, and monocytes/macrophages, all of which are types of white blood cells.
• T cells expressing the cell-surface protein CD4 are divided into two subsets: T helper (Th)1 cells, which are primarily involved in activating macrophages and inflammatory responses, and Th2 cells, which are primarily involved in stimulating antibody production by B cells.
• A small subset of B and T cells, known as memory cells, remain indefinitely after an infection and recognize specific antigens.
• Transforming growth factor-beta (TGF-β) is an anti-inflammatory cytokine produced by T cells and B cells that binds to TGF-βR1, 2, and 3, and acts on activated T and B cells to inhibit their proliferation, inhibit hematopoiesis, and promote wound healing.
• Memory cells are a small subset of B and T cells that remain indefinitely after an infection and recognize specific antigens.
• Helper T-cells are specialized lymphocytes that mature in the thymus and assist other T-cells and B-cells in performing their functions.
• Adaptive immune responses are initiated in peripheral lymphoid tissues, where T cells that encounter antigen proliferate and differentiate into antigen-specific effector cells, and B cells proliferate and differentiate into antibody-secreting cells.
• In peripheral lymphoid tissues, T cells that encounter antigen proliferate and differentiate into antigen-specific effector cells, while B cells proliferate and differentiate into antibody-secreting cells.
• Natural Killer (NK) cells contribute to the innate immune response by nonspecifically eliminating target cells, such as virus-infected or malignant cells, through apoptosis independently of T or B cells.
• T cells and B cells are the two primary cell types central to the adaptive immune response.
• IL-1 is classified as a pro-inflammatory cytokine, is produced by macrophages, B cells, and dendritic cells, binds to the CD121a receptor, targets B cells, NK cells, and T cells, and functions in pyrogenic activity, inflammation, cell proliferation, differentiation, and bone marrow cell proliferation.
• The bone marrow serves as a training ground for B-cells, and the thymus serves as a training ground for T-cells.
• The immune system consists of white blood cells categorized as lymphocytes (T-cells, B-cells, and NK cells), neutrophils, and monocytes/macrophages.
• While T-cells kill viruses, they also instruct B-cells to produce antibodies (immunoglobulin).
• The adaptive immune system involves T-cells and B-cells, which require training or education to learn not to attack the body's own cells.
• B cells that encounter antigen while migrating through a lymph node are arrested and activated with the assistance of activated T cells.
• Lymphocytes, including T cells and B cells, are involved in the inflammatory response.
• Natural Killer T (NKT) cells are considered part of the innate immune response because they act swiftly during infections to kill microorganisms or cells and produce cytokines without requiring the slower differentiation or proliferative processes associated with T and B cells.
• 1,25-dihydroxyvitamin D3 suppresses antibody production by B cells and inhibits the proliferation of T cells in vitro.

macrophages

Macrophages and B cells are both types of white blood cells {fact:2, fact:8} that function as antigen-presenting cells {fact:7, fact:12} and share the ability to produce various cytokines such as IL-38 {fact:5, fact:6} and IL-10 [1]. Furthermore, they interact within the immune system where B cells produce antibodies to mark pathogens for destruction by macrophages [2], and both are targets for regulation by T cell signaling {fact:3, fact:4, fact:11}. — 16 supporting facts

antibodies

• B cells, once activated, reproduce to increase in number and secrete large quantities of antibodies to neutralize pathogens.
• B lymphocytes (B cells) differentiate into plasma cells that secrete antibodies upon activation.
• Primary immunodeficiencies result from a defect in one or more elements or functions of the normal immune system, such as T cells, B cells, NK cells, neutrophils, monocytes, antibodies, cytokines, or the complement system.
• B cells develop from stem cells in the bone marrow, where they undergo maturation and training to ensure they do not produce antibodies against healthy tissues.
• When B cells encounter foreign germs (antigens), they mature into plasma cells to produce antibodies or into memory cells to facilitate a rapid response to future infections.
• B cells secrete antibodies to neutralize pathogens.
• B-cells are lymphocytes that arise in the bone marrow and differentiate into plasma cells, which produce immunoglobulins (antibodies).
• B cells, also known as B-lymphocytes or CD19/CD20 cells, are specialized immune system cells that function to produce antibodies (immunoglobulins or gamma-globulins).
• Plasma cells are the mature cells derived from B-cells that produce antibodies.
• Plasma cells are the mature form of B cells that produce antibodies and are located in the spleen and lymph nodes.
• B cells that secrete antibodies are also known as plasma cells.
• B cells produce antibodies that neutralize pathogens and promote their clearance by other immune cells.
• While T-cells kill viruses, they also instruct B-cells to produce antibodies (immunoglobulin).
• Helper T cells assist B cells in producing antibodies and assist killer T cells in attacking foreign substances.
• B cells produce antibodies, which are specialized proteins that recognize and bind to foreign proteins or pathogens to neutralize them or mark them for destruction by macrophages; this response is called humoral immunity.

immune system

B cells are a fundamental component of the immune system, as they are classified as a type of lymphocyte and white blood cell within that system [1], [2]. Furthermore, defects in B cells are recognized as a cause of primary immunodeficiencies affecting the immune system [3], and they serve the specific immune function of producing antibodies [4]. — 4 supporting facts

infection

B cells are directly involved in the immune response to an infection, as they mature into memory cells that persist after an infection to provide long-term immunity [1], [2], and [3]. — 3 supporting facts

neutrophils

Neutrophils and B cells are both classified as types of white blood cells within the immune system, as established in [1] and [2]. Furthermore, both are identified as critical components whose functional defects can lead to primary immunodeficiencies according to [3]. — 3 supporting facts

inflammation

Inflammation and B cells are related because B cells produce IL-1, a pro-inflammatory cytokine that functions in inflammation [1], and IL-1 also targets B cells [1]. — 1 supporting fact
