Cell-mediated immunity is directed primarily at microbes that survive in phagocytes and microbes that infect non-phagocytic cells. It is most effective in removing virus-infected cells, but also participates in defending against fungi, protozoans, cancers, and intracellular bacteria.

What happens in cellular immune response?
Antibodies produced by the B cells will bind to antigens, neutralizing them, or causing lysis (dissolution or destruction of cells by a lysin) or phagocytosis. Cellular immunity occurs inside infected cells and is mediated by T lymphocytes.
What is difference between humoral and cellular immunity?
Humoral immunity plays a major role in recognizing antigen or any foreign particle and in producing antibodies against it. ... Humoral immunity secretes antibodies to fight against antigens, whereas cell-mediated immunity secretes cytokines and no antibodies to attack the pathogens.

Which cells provide cellular immunity?
Cellular immunity is mediated by T lymphocytes, also called T cells. Their name refers to the organ from which they're produced: the thymus. This type of immunity promotes the destruction of microbes residing in phagocytes, or the killing of infected cells to eliminate reservoirs of infection.
How does cellular immunity protect the body?
Cell-mediated immunity is directed primarily at microbes that survive in phagocytes and microbes that infect non-phagocytic cells. It is most effective in removing virus-infected cells, but also participates in defending against fungi, protozoans, cancers, and intracellular bacteria.
What is the main goal of cellular immunity?
Cellular immunity is most effective against cells infected with viruses, intracellular bacteria, fungi and protozoans, and cancerous cells. It also mediates transplant rejection.
Can active immunity last a lifetime?
It can take days or weeks after the first exposure for active immunity to develop. But once it does so, the protection can last an entire lifetime. Active immunity can occur in one of two ways: naturally or via an immunization.
What is an example of humoral immunity?
Innate immunity also comes in a protein chemical form, called innate humoral immunity. Examples include the body's complement system and substances called interferon and interleukin-1 (which causes fever). If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system.
Why is it called humoral immunity?
Humoral immunity is named so because it involves substances found in the humors, or body fluids. It contrasts with cell-mediated immunity.
What are the 2 types of immune response?
Although all components of the immune system interact with each other, it is typical to consider two broad categories of immune responses: the innate immune system and the adaptive immune system. Innate immune responses are those that rely on cells that require no additional “training” to do their jobs.
What are four basic line of Defence mechanism?
The immune system includes three lines of defense against foreign invaders: physical and chemical barriers, nonspecific resistance, and specific resistance. The first line of defense are the physical and chemical barriers, which are considered functions of innate immunity.
What is a normal immune response?
Antigens may also exist on their own—for example, as food molecules or pollen. A normal immune response consists of the following: Recognizing a potentially harmful foreign antigen. Activating and mobilizing forces to defend against it.
