White blood cells, more specifically B-lymphocytes.
T cells are specifically responsible for cell-mediated immunity. They include cytotoxic T cells, helper T cells, and regulatory T cells, each playing a crucial role in orchestrating the immune response against pathogens or abnormal cells.
B lymphocytes are the formed elements most directly responsible for humoral immunity. They produce antibodies that circulate in the bloodstream and bind to antigens, marking them for destruction by other immune cells.
Helper cells (e.g. T helper cells) play a role in activating the immune response by coordinating and stimulating other immune cells like killer cells (e.g. cytotoxic T cells) to target and destroy abnormal cells. Killer cells directly eliminate infected or abnormal cells by inducing programmed cell death. This coordinated effort helps the immune system effectively rid the body of threats.
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. Also humoral immunity provides a defense against antigens and pathogens in body fluids whereas cell-mediated immunity protects from abnormal cells and pathogens inside living cells.
Cell-mediated immunity is primarily carried out by T cells, specifically cytotoxic T cells and helper T cells. These T cells are responsible for recognizing and targeting infected or abnormal cells in the body, helping to destroy pathogens and mount an immune response.

Cell-mediated immunity. T cells play a key role in cell-mediated immunity by directly attacking infected cells or coordinating the immune response.
Helper T cells and cytotoxic T cells are the main types of T cells involved in cellular immunity. Helper T cells help activate other immune cells, while cytotoxic T cells directly kill infected or abnormal cells. Both types are important for coordinating and executing the immune response against pathogens.
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.
The white blood cells primarily responsible for adaptive immunity are lymphocytes, specifically B cells and T cells. B cells are responsible for producing antibodies that target specific pathogens, while T cells are involved in directly killing infected cells and coordinating the immune response. Together, they provide a tailored and long-lasting defense against specific antigens.

Cytoxic T-Cells differentiate and produce identical clones. They travel to the infection site and release enzymes directly into the pathogens, causing them to lyse and die.
