What do T-Cells recognize?

  1. Antigens displayed on the Langerhans cell

  2. Changes in temperature

  3. Pressure changes

  4. Levels of hydration

The correct answer is: Antigens displayed on the Langerhans cell

T-Cells, which are a crucial part of the immune system, specifically recognize antigens displayed on specialized cells, including Langerhans cells. Langerhans cells are a type of dendritic cell found in the skin and play a key role in sensing foreign substances and presenting antigens to T-Cells. This recognition is vital for initiating an immune response, enabling the body to defend against pathogens like bacteria and viruses. The other options do not relate to the function of T-Cells. T-Cells do not recognize changes in temperature, pressure, or levels of hydration, as these are not related to their primary role in mediating immune responses against antigens. Thus, the recognition of antigens by T-Cells is essential in understanding how the immune system identifies and responds to threats.
