| - | <h1>Modeling</h1>
| |
| - | For the modeling part we considered three main parts:
| |
| - | <ul>
| |
| - | <li>the virus production
| |
| - | <li>the infection of a target cell
| |
| - | <li>the therapy
| |
| - | </ul>
| |
| - | For the first two models we assumed reactions according to the law of mass action to create a model of ordinary differential equations (ODE).

| - | <h3>Reaction Scheme</h3>
| |
| - | Reducing the complexity of virus production we divide the cell into three compartments: the <b>extracellular matrix</b> (all quantities with the index <i>ext</i>), the <b>cytoplasm</b> (<i>cyt</i>) and the <b>nucleus</b> (<i>nuc</i>). Four plasmids are transfected - the plasmid coding for the <b>helper proteins</b> (<i>helper</i>), the <b>gene of interest</b> (<i>goi</i>) and two types of plasmids coding for the <b>capsid proteins</b> (<i>capwt</i> [wild type], <i>capmod</i> [modified]).<br>
| |
| - | The plasmids are transported into the nucleus where gene expression is initiated. Processed mRNA is transported into the cytoplasm and proteins are produced. Containing a nuclear localization sequence proteins are relocated into the nucleus where capsid assembly occurs. The gene of interest is replicated by cellular polymerases and single stranded DNA (<i>ssDNA</i>) is encapsidated into the preformed capsids forming infectious viral particles (<i>V</i>).<br>
