T cells are critical to generate early control and clearance of many viral infections of the respiratory system ().Recent studies in transgenic mouse models provided evidence that T cells are also important for viral clearance and disease resolution after SARS-CoV-2 infection ().Hence, it is expected that T cell activation has emerged as a hallmark of acute COVID-19, probably as a consequence . We can see how this works by considering adrenaline signaling in muscle cells. The glucose is available for use by the muscle cell in response to a sudden surge of adrenalinethe fight or flight response. Molecular Biology of the Cell. This type of receptor spans the plasma membrane and performs signal transduction, in which an extracellular signal is converted into an intercellular signal. Through regulation of these enzymes, a muscle cell rapidly gets a large, ready pool of glucose molecules. In some cases, scaffolding proteins themselves may activate relay proteins. The response starts by activating antigen-specific cytotoxic T-lymphocytes or CTLs which can destroy body cells which show epitopes of foreign antigen on their surfaces such as cells with intracellular bacteria, cancer cells which show tumor antigens and virus-infected cells. How could activating a transcription factor cause long-term cellular changes? Receptors generate a cellular response upon binding their specific ligand.
