-Lupus erythmeatosus

Lupus erythmeatosus

Acantholysis

Dissolution of the intercellular bridges of the prickle cell layer of the epithelium

Acquired immune response

A response of the body to injury that has memory of past exposure to a foreign substance and responds more quickly to a foreign substance when encountered a second time

Antibody

A protein molecule, also called an immunoglobulin which is produced by plasma cells and reacts with a specific antigen

Antigen

Any substance able to induce a specific immune response

Autoimmune disease

A disease characterized by tissue injury caused by a humoral cell or cell-medaited immune response against constituents of the body's own tissues.

B lymophocyte (B cell)

A lymphocyte, that mature without passing through the thymus; the B cell can later develop into a plasma cell that produces antibodies

Cell-mediated immunity

Immunity in which the predominant role is played by T lymphocytes

Cytokines

Cell product produced by the cells involved in the immune response

Humoral Immunity

Immunity in which B lymphocytes and antibodies plat the predominant role

Hypersensitivity

A state of altered reactivity in which the body reacts to a foreign agent with an exaggerated immune response.

Immune complex

A combination of antibody and antigen

Immunodeficiency

A deficiency of the immune response resulting from hypoactivityor decreased numbers of lymphoid cells

Immunoglobulin

A protein, also called and antibody, synthesized by plasma cell in response to a specific antigen

LE cell

A cell that is a characteristic of lupus erythmeatosus and other autoimmune diseases; it is a mature neutrophil that has phagocytized a spherical inculsion derived from another neutrophil

Lymphoid tissue

Tissue composed of lymphocytes supported by a meshwork of connective tissue

Macrophage

A large tissue-bound mononuclear phagocyte derived from monocytes circulating in blood; macrophages become mobile when stimulated by inflammation and interact with lymphocytes in an immune response

Mucositis

Mucosal inflammation

Natural killer cell (NK cell)

A lymphocyte that is part of the body's initial innate immunity which by unknown mechanisms is able to directly destroy cells recognized as foreign
