Final answer:
During bacterial or viral infections, certain genes in the host cells are activated, leading to the production of Acute Phase Proteins (APPs) or Acute Phase Reactants (APRs). Examples of APPs include C-reactive protein (CRP), fibrinogen, and serum amyloid A (SAA). The role of TYK2 gene variations in infections is associated with altered susceptibility.
Step-by-step explanation:
Infections caused by bacterial or viral pathogens can lead to the activation of certain genes in the host cells, resulting in the production of specific proteins known as Acute Phase Proteins (APPs) or Acute Phase Reactants (APRs). These proteins play a crucial role in the immune response to infection. Examples of APPs that are commonly recorded during bacterial or viral infections include C-reactive protein (CRP), fibrinogen, and serum amyloid A (SAA).
As for TYK2, it is a gene that encodes a protein called Tyrosine Kinase 2, which is involved in signaling pathways related to the immune response. However, there is not enough evidence to suggest that TYK2 specifically results in increased infection. Instead, variations in the TYK2 gene have been associated with altered susceptibility to certain infectious diseases. For example, some genetic variations in TYK2 have been linked to increased susceptibility to bacterial infections like tuberculosis.
