Killer t cells are activated by helper t cells. The Helper t cells are alerted by the macrophage that has engulfed the virus. It grows antigens to alert the helper t cells. The killer t cells are like white blood cells, there purpose is to fight pathogens.
T helper cells are activated in the immune response process when they encounter antigens presented by antigen-presenting cells, such as dendritic cells. This interaction triggers the T helper cells to proliferate and differentiate into specific subsets that help coordinate and regulate the immune response.

helper T cells B cells so the answer is B for Plato users
Helper T cells in the immune response are activated by antigens presented by antigen-presenting cells, such as dendritic cells. This activation process helps coordinate and regulate the immune response against pathogens.
Helper T cells, also known as CD4+ T cells, play a crucial role in activating killer T cells and B cells. Helper T cells recognize antigens presented by antigen-presenting cells, which triggers them to release signals that stimulate the activation and proliferation of killer T cells and B cells to mount an immune response against the specific pathogen.
(t-cells) are involved in cell mediated immunity that can have memory of previous antigens(non self) that have invaded our body. cytotoxic tcells release preforin that destroy tumor cells or antigens helper tcells release cytokines/interlukins that help in more tcell differentiation
Antigen-presenting cells, such as dendritic cells, macrophages, and B cells, engulf antigens and present fragments of them on their cell surfaces. These antigens are then recognized by T cells, particularly CD4+ helper T cells or CD8+ cytotoxic T cells, which play a key role in initiating an immune response against the antigen.
The cells which are involved in the production of antibodies are known as B cells. These are effector cells which will secrete anybodies and activate the antigens.
Lymphocytes that act directly on antigens to destroy them or produce chemicals that are toxic to them are called T4 cells. They are also known as T helper cells.
Major histocompatibility complex (MHC) molecules display antigens on the surface of cells. There are two main classes: MHC class I, which presents antigens to CD8+ cytotoxic T cells, and MHC class II, which presents antigens to CD4+ helper T cells. These molecules play a crucial role in the immune response by enabling the recognition of foreign substances by T cells.
It is a type of leukocyte, or white blood cell, but it has no ability to ingest or destroy invading bacteria. It activates other white blood cells or antibodies to react with the invading organism.
