Antigens that are free-floating in the environment and not presented by host cells.

Antigens processed and presented by antigen presenting cells for T cell activation.

Immune cells that process and present antigens, including dendritic cells, macrophages, and B cells.

A type of antigen presenting cell that processes and presents antigens to T cells.

Immune cells that can act as antigen presenting cells, processing and presenting antigens.

Immune cells that respond only to antigens presented by antigen presenting cells.

Immune cells that respond only to free antigens and can also act as antigen presenting cells.
