Instead, plasma cells are identified through flow cytometry by their additional expression of CD138, CD78, and the Interleukin-6 receptor. In humans, CD27 is a good marker for plasma cells; naïve B cells are CD27−, memory B-cells are CD27+ and plasma cells are CD27++. [5] The surface antigen CD138 (syndecan-1) is expressed at high levels. [6]
The physiology of plant memory is documented in many studies and is understood to have four main physiological mechanisms that work together in synchrony to provide the plant with basic memory functions, and are thought to be precursors to advanced memory functions found in animals. These four mechanisms are the storing and recalling ...
Long-lived plasma cells (LLPCs) are a distinct subset of plasma cells that play a crucial role in maintaining humoral memory and long-term immunity. [1] They continuously produce and secrete high-affinity antibodies into the bloodstream, conversely to memory B cells , which are quiescent and respond quickly to antigens upon recall.
Plant intelligence is a field of plant biology which aims to understand how plants process the information they obtain from their environment. [ 2 ] [ 3 ] Plant intelligence has been defined as "any type of intentional and flexible behavior that is beneficial and enables the organism to achieve its goal".
Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism . [ 1 ] Animal cells , plant cells and microorganism cells show similarities in their functions even though they vary in structure.
Differentiation of memory B cells into plasma cells is far faster than differentiation by naïve B cells, which allows memory B cells to produce a more efficient secondary immune response. [4] The efficiency and accumulation of the memory B cell response is the foundation for vaccines and booster shots.
Meristematic tissues contain cells that continue to grow and differentiate throughout the plant's lifetime. Shoot apical meristem gives rise to flowers and leaves while root apical meristem grows into roots. These components are crucial to general plant growth and are the harbingers of development.
