Question

Which of the following is not characteristic of the early stages of a localized inflammatory response?

Options

• Increased permeability of capillaries

• Attack by cytotoxic T-cells

• Release of histamine

• Dilatation of blood vessels

Answer 1

Attack by cytotoxic T-cells

Explanation:

The early stages of a localized inflammatory response are characterized by increased permeability of capillaries, release of histamine, and dilation of blood vessels. These changes facilitate the migration of immune cells and plasma proteins to the site of injury or infection. Attack by cytotoxic T-cells is not a characteristic of the early inflammatory response; cytotoxic T-cells are involved later in cell-mediated immunity aimed at killing infected cells, not in the initial inflammation process.
