Plasma cells with Dutcher and Russell bodies (H&E stain, 100×, oil) Plasma cells are large lymphocytes with abundant cytoplasm and a characteristic appearance on light microscopy. They have basophilic cytoplasm and an eccentric nucleus with heterochromatin in a characteristic cartwheel or clock face arrangement.
Plasma cell: Lymphocyte: B cell: Plasma B cells; Effector B cells; Plasmocytus; 8-10 Active B cells that produces large amounts of antibodies [4] [15] Memory B cell: Lymphocyte: B cell: MBC; 8-10 Memorizes the characteristics of the antigens; Triggers an accelerated and robust secondary immune response [4] [16] Killer T cell: Lymphocyte: T cell ...
Once a B cell encounters its cognate (or specific) antigen (and receives additional signals from a helper T cell (predominately Th2 type)), it further differentiates into an effector cell, known as a plasma cell. [3] Plasma cells are short-lived cells (2–3 days) that secrete antibodies. These antibodies bind to antigens, making them easier ...
B cell activation: from immature B cell to plasma cell or memory B cell Basic B cell function: bind to an antigen, receive help from a cognate helper T cell, and differentiate into a plasma cell that secretes large numbers of antibodies. B cell activation occurs in the secondary lymphoid organs (SLOs), such as the spleen and lymph nodes. [1]
The plasma collisionality is defined as [4] [5] =, where denotes the electron-ion collision frequency, is the major radius of the plasma, is the inverse aspect-ratio, and is the safety factor. The plasma parameters m i {\displaystyle m_{\mathrm {i} }} and T i {\displaystyle T_{\mathrm {i} }} denote, respectively, the mass and temperature of the ...
Plasma and serum are both derived from full blood, but serum is obtained by removing blood cells, fibrin clots, and other coagulation factors while plasma is obtained by only removing blood cells. [22] Blood plasma and blood serum are often used in blood tests. Tests can be done on plasma, serum or both. [23]
Russell bodies are inclusion bodies usually found in atypical plasma cells that become known as Mott cells. [1] Russell bodies are eosinophilic , homogeneous immunoglobulin (Ig)-containing inclusions usually found in cells undergoing excessive synthesis of Ig; the Russell body is characteristic of the distended endoplasmic reticulum .
Downey type II cell is the most common type of reactive lymphocyte. In general, those cells may vary in morphologic detail as well as surface marker characteristics since this is the result of a polyclonal immune response to antigenic stimulation.
