What are the functions of t memory cells

T cells provide an immune response against the antigen by attacking infected cells and provide immediate response against future infection, by producing antibodies.

Explanation:

T cells or the T lymphocytes are one of the major components of the acquired immune system. They are important to have an immune response against pathogens.

T cells act against intracellular antigens such as protozoa, viruses, and bacteria (intracellular), and providing help for the antibody response for extracellular pathogens. They are of four main types - CD4+ helper, CD8+ cytotoxic cells, memory T cells, and NK cells.

These cells release cytokines to directly attack infected cells and stimulate the production of more T cells. Some of these T cells will become memory T cells in preparation for secondary infections, and others become cytotoxic T cells to attack infected cells.

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.
