The difference between humoral immunity and cell-mediated immunity is that humoral immunity uses B cells and T cells whereas mediated immunity only uses the T cells.

An allergic response is an immune over reaction to a harmless allergen such as pollen which will adversely affect the host, when the allergen is pollen this causes hayfever.
the parts of the human immune system. It has three parts: cellular, humoral, and nonspecific.
James L. Biesecker has written: 'Cellular and humoral immunity after allogeneic transplantation in the rat'
Humoral immunity is effected by antibodies produced by plasma cells toward a specific foreign antigen. Cellular immunity does not directly involve antibodies, but refers to cellular destruction of alien cells/tissues by production of cytotoxins locally, typically the latter are produced by T-lymphocytes and natural killer cells.
how they respond to and dispose of invaders.
Humoral immunity is mediated by antibodies.
