What type of lymphocyte can produce antibodies

MALTs are lymphoid tissues found in parts of the body where mucosa is present, such as the intestines, eyes, nose, skin and mouth. They contain lymphocytes and macrophages that defend against pathogens attempting to enter from outside the body.

Many cells work together as part of the innate non-specific and adaptive specific immune system. Immune cells are sometimes called white blood cells or leukocytes. Figure 2. Blood Cells. Granulocytes are a type of leukocyte that contain granules in their cytoplasm containing enzymes. Neutrophils, basophils and eosinophils are types of granulocytes. Neutrophils are considered the first responders of the innate immune system. Neutrophils and macrophages circulate though the blood and reside in tissues watching for potential problems.

Cells of the adaptive immune system also called immune effector cells carry out an immune function in response to a stimulus. Natural killer T lymphocytes and B lymphocytes are examples of effector cells. For example, activated T lymphocytes destroy pathogens via cell-mediated response. Activated B cells secrete antibodies that aid in mounting an immune response. Effector cells are involved in the destruction of cancer.

Figure 3. Non-effector cells are antigen-presenting cells APCs , such as dendritic cells, regulatory T cells, tumor-associated macrophages and myeloid-derived suppressor cells. Non-effector cells cannot cause tumor death on their own.

Non-effector cells prevent the immune action of the effector cells. In cancer, non-effector cells allow tumors to grow. Tumor antigens can trigger adaptive immunity. Cells, such as macrophages, dendritic cells and B cells, that can process protein antigens into peptides. These peptides can then be presented along with major histocompatibility complex to T-cell receptors on the surface of the cell. Figure 4. Special proteins created by white blood cells that can kill or weaken infection-causing organisms.

Antibodies travel through the blood stream looking for specific pathogens. A basophil is a type of phagocytic immune cell that has granules. Inflammation causes basophils to release histamine during allergic reactions. A B lymphocyte is a type of white blood cell that develops in the bone marrow and makes antibodies.

Activated B cells that produce antibodies. Only one type of antibody is produced per plasma B cell. Interferon-alpha2b is a cytokine produced in a laboratory using recombinant DNA technology and is used in the treatment of malignant melanoma. Dendritic cells are antigen-presenting cells APCs. Antigen is combined with major histocompatibility complex and presented on a dendritic cell to active T and B lymphocytes.

An eosinophil is a type of immune cell leukocyte, or white blood cell. They help fight infection or cause inflammation. Granulocytes including eosinophils, neutrophils and basophils are a type of white blood cell that releases toxic materials, such as antimicrobial agents, enzymes, nitrogen oxides and other proteins, during an attack from a pathogen. The primary effector cell of innate immunity; the first responders of the immune system. They interact with signals from other cells activating and inhibitory.

Type of white blood cell that is involved with the immune system. T lymphocytes mature in the thymus and differentiate into cytotoxic, memory, helper and regulatory T cells. The T cells are grown and modified in a lab to include special receptors chimeric antigen receptor that can recognize and attack cancer cells. Activated cytotoxic T cells can migrate through blood vessel walls and non-lymphoid tissues.

They can also travel across the blood brain barrier. Derived from activated cytotoxic T cells, memory T cells are long-lived and antigen-experienced. One memory T cell can produce multiple cytotoxic T cells.

After activated cytotoxic T cells attack the pathogen, the memory T cells hang around to mitigate any recurrence. Helper T cells secrete cytokines that help B cells differentiate into plasma cells. These cells also help to activate cytotoxic T cells and macrophages.

Lymphocytes are immune cells found in the blood and lymph tissue. T and B lymphocytes are the two main types. Macrophages are large white blood cells that reside in tissues that specialize in engulfing and digesting cellular debris, pathogens and other foreign substances in the body. Large white blood cells that reside in the blood stream that specialize in engulfing and digesting cellular debris, pathogens and other foreign substances in the body.

Monocytes become macrophages. When immature myeloid cells cannot differentiate into mature myeloid cells, due to conditions like cancer, expansion of myeloid-derived suppressor cells occurs, and the T-cell response can be suppressed. A type of white blood cell, granulocyte, and phagocyte that aids in fighting infection. Neutrophils kill pathogens by ingesting them. Macrophages are the body's first line of defense and have many roles. A macrophage is the first cell to recognize and engulf foreign substances antigens.

Macrophages break down these substances and present the smaller proteins to the T lymphocytes. T cells are programmed to recognize, respond to and remember antigens. Macrophages also produce substances called cytokines that help to regulate the activity of lymphocytes.

Dendritic cells are known as the most efficient antigen-presenting cell type with the ability to interact with T cells and initiate an immune response.

Dendritic cells are receiving increasing scientific and clinical interest due to their key role in the immune response and potential use with tumor vaccines.

There are different types of white blood cells that are part of the immune response. Neutrophils or granulocytes are the most common immune cells in the body. With an infection, their number increases rapidly. They are the major components of pus and are found around most common inflammations. Their job is to eat and destroy foreign material.

Basophils and eosinophils are white blood cells that contain large granules inside the cell. They interact with certain foreign materials. Their increased activity may lead to an allergic reaction. The immune response is a coordinated effort. All of the immune cells work together, so they need to communicate with each other.
