It s often cancer s spread, not the original tumor, that poses the disease s most deadly risk. And yet metastasis is one of the most poorly understood aspects of cancer biology, says Kamen Simeonov, an M.D.-Ph.D. student at the University of Pennsylvania Perelman School of Medicine.
In a new study, a team led by Simeonov and School of Veterinary Medicine professor Christopher Lengner has made strides toward deepening that understanding by tracking the development of metastatic cells. Their work used a mouse model of pancreatic cancer and cutting-edge techniques to trace the lineage and gene expression patterns of individual cancer cells. They found a spectrum of aggression in the cells that arose, with cells that
The claim: Spike proteins from coronavirus vaccines are dangerous toxins that cause damage in the body
A Canadian immunologist who says he s pro-vaccine has recently become the source of misinformation about the safety of coronavirus vaccines.
Text in a June 3 Instagram photo says the coronavirus spike protein resulting from vaccination is a toxin. The post cites a doctor as evidence. Doctor on COVID Vax: We Screwed-Up. We didn t realize the Spike Protein is a TOXIN, the text says. Does this mean everyone vaccinated is manufacturing their own Spike Protein Toxins in their own bodies?
The post is one of dozens of similar claims that have circulated on Facebook and Instagram over the past few weeks, according to CrowdTangle, a social media insights tool. The most widely shared version stemmed from a May 31 article by LifeSite News, which has previously made false claims about the safety of coronavirus vaccines.
Your immune system is always busy fighting incoming threats. It consists of a system of cells, and when there is a shortage of cells, it affects the performance of the immune system.

Your immune system is always busy fighting incoming threats. It consists of a system of cells, and when there is a shortage of cells, it affects the performance of the immune system.
This is seen in e.g. cancer patients following chemotherapy. This is because chemotherapy targets all the cells in your body, including the stem cells in your bone marrow, which were meant to develop into new immune cells. This means that the immune system then lacks cells to fight new infections.
There are drugs that can harvest stem cells from the bone marrow, so that they can be returned to the patients after treatment. They then develop into new immune cells, enabling the body to once again fight incoming threats. But previously, we lacked detailed knowledge of how these drugs worked.
