Section 3: Adaptive Immunity (PART 2)

Unlike B cells, T lymphocytes are ________ to recognize pathogens without assistance.

• able

• unable

APC

• Antigen Presenting Cells

• Anterior Particulate Cranium

• Antigen Particle Caption

• Anterior Pallate Cruciate

Antigen Presenting Cells...

• detects, engulfs, and informs the adaptive immune response about an infection

• are part of cell mediated immunity

• are part of humoral immunity

• amplify the immune response- act like an alarm

• engulf antigens and present pieces of the antigen to other immune cells.

Symptoms are more likely to be less severe in the...

• primary infection response

• secondary infection response

Release cytokines which induce immune response

• Helper T Cells

• Cytotoxic T Cells

• Regulatory T Cells

• Memory T Cells

• Supressor T Cells

Stimulate B cells to start the humoral response

• Helper T Cells

• Cytotoxic T Cells

• Regulatory T Cells

• Memory T Cells

• Supressor T Cells

Detects APC (antigen presenting cell) signals and directly kills the infected cells
