How are lymphocytes able to distinguish self from nonself?
Lymphocytes are part of the human body's innate immune system. Natural killer cells seek out and destroy foreign cells by distinguishing surface molecules of major histocompatibility complex class.
distinguish self from nonself
An immune response is based on the ability to distinguish molecules that are part of the body ("self") from those that are not ("nonself," or foreign). Such molecules that can elicit an immune response are called antigens.
So it won't attack 'self'.
B-lymphocytes are a type of white blood cell of the immune system that synthesize antibodies to protect the organism from foreign/non-self antigens.
The body's own cells

Self Image is how one think of themselves physically. Self Esteem is how ones thought life is. Negative or Positive.
by identifying the MHC (major histo compatibility complex) receptors on cells
Because it is more likely that a relative will have the same MHCs (major histocompatibility complexes) on their cells. When immune cells patrol the body they will bind these complexes which tell them whether the cell they are binding is 'self" or "nonself". If they bind a MHC which they percieve as nonself, they may initate an immune response leading to rejection of the graft
Directly from my anatomy and physiology book - Marieb & Hoehn Eighth Edition: "Lymphocytes originate in red bone marrow from hematopoietic stem cells." " B cells become immunocompetent and self-tolerant in the bone marrow."
The thymus matures T lymphocytes (T cells) which identify foreign antigens. This is also where T cells that would be able to bond with self-antigens (would attack the bodies healthy cells) are weeded out and destroyed.
If it did not it would begin to destroy itself. This is what happens in autoimmune disorders. It should only attack non-self cells, etc.
Most plants do not self pollinate.
Called into action when nonspecific methods are not enough and infection becomes widespread Types of cells involved in the immune system: Macrophages - engulf foreign objects Inform T lymphocytes at a specific antigen is present Helper T cells - produce and secrete chemicals which promote large numbers of effector and memory cells Cytotoxic T cells - T lymphocytes that eliminate infected body cells and tumor cells B cells - produce antibodies (secrete them in the… Read More
In case of autoimmune disorders, the immune system cannot distinguish between "self" cells and invader cells
The process of pollination from same flower is called self-pollination. the process of pollination from another flower of same breed is called cross-pollination.
Self confidence is being able to conduct yourself clearly and with certainty in everything that you do.

im·mu·nol·o·gy (ĭm'yə-nŏl'ə-jē) n. The branch of biomedicine concerned with the structure and function of the immune system, innate and acquired immunity, the bodily distinction of self from nonself, and laboratory techniques involving the interaction of antigens with specific antibodies.

White blood cells (lymphocytes) are the primary agents of the immune response. The various types are as follows: 1. B cells. These originate and mature in the bone marrow ( B for bone). They respond to antigen markers with their special antigen receptors (antibodies) on their surface. Antibodies inactivate antigens by binding to them. Inactivation is followed by phagocytosis. Also they stimulate complement proteins to bring about the lysis of pathogens. When a B cell… Read More

Able to self replicate
At the heart of the immune response is the ability to distinguish between 'self' and 'non-self.' Every cell in your body carries the same set of distinctive surface proteins that distinguish you as 'self.' Normally your immune cells do not attack your own body tissues, which all carry the same pattern of self-markers. This set of unique markers on human cells is called the major histocompatibility complex (MHC). There are two classes: MHC Class I… Read More

ATF fluid is automatic transmission fluid. It is used in vehicles that have automatic or self shifting transmissions. To distinguish it from other engine fluids, it is usually red or green.
A person who has a mild personality requires self control so they do not get angry and have bursts of emotions. If you have self control you will be able to handle stressful situations more easily.
Neither. Alloreactivity has to do with a lymphocytes reacting to a foreign antigen. Positive and negative selection are processes of central tolerance which is to say that they deal with a T cell's ability to bind self-antigen.
it is self-pollinating

At the heart of the immune response is the ability to distinguish between "self" and "non-self." Every cell in your body carries the same set of distinctive surface proteins that distinguish you as "self." Normally your immune cells do not attack your own body tissues, which all carry the same pattern of self-markers; rather, your immune system coexists peaceably with your other body cells in a state known as self-tolerance.
