Document Summary
Whena virus infects a cell, nucleic acid must be uncoated and gain access to the cellular machinery of the cell. Virus life cycle: attachment, penetration with entry of the nucleic acid into the cell, early expression of virus genes (positive ra) A viral genome persists within the host cell. Expression of no or few viral genes. E. g. cold sores (herpes simplex virus), chicken pox/shingles (herpes zoster virus) appear during immunocompromise. Eukaryotic, single cell to chain of cells. Antifungal drugs because the human cell is like fungi, these drugs are more toxic to humans than antibiotics. Pge-2 prostaglandins causing fever trying to raise the thermostat of the brain. Night sweats thermostat has declined due to sleeping, so inflammatory processes are going up and down, so sweats to get rid of excess heat. Lymph nodes dendrites present the epitope body part to the t helper cell (mhc molecules present this to this)
