Comparison of XMRV infection

Cell	Type	XMRV level (pg/ug total RNA)
Progenitor	Primary neuronal	50.0
Progenitor-derived Neuron	Primary neuronal	90.0
Progenitor-derived Astrocyte	Primary neuronal	7.2
Jurkat	Immortalized T-cell	4.8
DU145	Human prostate carcinoma	3.8
LNCaP	Human prostate adenocarcinoma	516
293T	Human embryonic kidney	0.158

Neuronal and non-neuronal cells were exposed with XMRV (10⁷ copies/mL) for two hours. Four days post-infection, XMRV levels were measured from the total RNA.
