I still have the mind of a 13 year old, even when reading about awesome new cancer treatments.
'Sticky balls' may stop cancer spreading from the BBC.
But seriously, this report is pretty interesting. Basically, the researchers created nanoscale liposomes with a cancer killing protein, TRAIL (=D! Doubly interesting for me since I've also recently started doing some studies on TRAIL for my thesis!).
Figure 1A from their paper.
When they tested these constructs with human blood and in the circulation of mice, they found it pretty damn effective at killing cancer cells.
Still needs to be tested in actual humans, but it would be pretty awesome to be able to use this method to kill circulating tumor cells in order to help prevent metastases.
