Inflammation triggers vasodilation and increased permeability through various molecules like prostaglandins, bradykinin, leukotrienes, nitric oxide, cytokines, platelet-activating factor, and histamine. Chemokines attract immune cells like neutrophils and monocytes, which then engage in phagocytosis and release inflammatory mediators like cytokines and chemokines, ultimately contributing to the acute inflammatory response.

Cell communication in multicellular organisms involves autocrine, paracrine, and endocrine signaling. Autocrine signaling enables a cell to regulate its own activity by releasing signaling molecules. Paracrine signaling affects nearby cells, while endocrine signaling releases molecules into the bloodstream, affecting distant target cells in tissues or organs.
Healthy Habits Promote a Healthy Immune System
A healthy immune system is crucial to well-being. Essential factors for its maintenance include a balanced diet rich in essential nutrients; regular hydration, exercise, and sleep; weight management; good hygiene practices; up-to-date vaccinations; moderate alcohol intake; and avoidance of smoking. These operate synergistically, and individualized healthcare advice can provide optimum support for immunity.
