% DISCUSSION 2nd mouse model
% TODO try and find literature explaining what the ideal ratio is
When testing \gls{car} T cells at earlier timepoints relative to day 14 as used
in the first \invivo{} experiment, we noted that none of the \gls{car}
treatments seemed to work as well as they did in the first experiment. However,
at day 14, we should note that the number of \gls{car} T cells injected in the
second experiment was lower than the lowest dose in the first for both bead and
\gls{dms} (\cref{fig:mouse_timecourse_qc_car,tab:mouse_dosing_results}). While
the \ptmemp{} generally increases with earlier timepoints in the second
experiment, the first experiment suggests that \ptmemp{} may not be the primary
driver in this particular model
(\cref{fig:mouse_timecourse_qc_mem,fig:mouse_dosing_qc_mem}). As with the first
experiment, the \pthp{} seems to be higher overall in the \gls{dms} group than
the bead group (\cref{fig:mouse_dosing_qc_cd4,fig:mouse_timecourse_qc_cd4}), and
this may explain the modest advantage that the \gls{dms} T cells seemed to have
in the second experiment in slowing the progression of tumor burden.
