Sentences with phrase «surrounding healthy cells»

Melanoma cells become drug resistant by using surrounding healthy cells to provide a «safe haven» from treatment, according to new research published in Cancer Cell.

The team's system has another advantage: CIK cells burrow deep into tumor tissue; that means the virus shouldn't harm surrounding healthy cells.

The Kanzius RF Machine transmits focused radio waves to these nanoparticles, which respond by releasing heat and incinerating infected cells while leaving the surrounding healthy cells intact.

In a bid to progress beyond the shotgun approach to fighting cancer — blasting malignant cells with toxic chemicals or radiation, which kills surrounding healthy cells in the process — researchers at the Harvard - MIT Division of Health Sciences and Technology (HST) are using nanotechnology to develop seek - and - destroy models to zero in on and dismantle tumors without damaging nearby normal tissue.

Not exact matches

But in the following hours and days, the body's self - defense mechanisms backfire: White blood cells come in to clean up dead tissue, which causes massive inflammation, which in turn triggers healthy cells in the surrounding tissue to self - destruct in a process called apoptosis.

This early stage research will explore how the virus targets stem cells and provide the starting point to develop new treatments that seek out the tumour and spare the surrounding healthy brain tissue.

One reason for this is that the tumour cells invade surrounding, healthy brain tissue, which makes the surgical removal of the tumour virtually impossible.

Within that sting lies a peptide called chlorotoxin, which has an unusual property — it sticks strongly to tumour cells while ignoring surrounding healthy tissue, by binding to a cancer - specific protein called matrix metalloproteinase - 2.

But working with human smooth muscle cells isolated and grown from the healthy parts of airway tissue surrounding excised tumors, Benjamin Kalbe and his colleagues applied a large number of odor molecules and watched two of them activate the muscle cells.

Writing in 2014 in the European Journal of Neuroscience, Leuner and colleagues reported that in rats with symptoms of postpartum depression (induced by stress during pregnancy, a major risk factor for postpartum depression in women), nerve cells in the nucleus accumbens atrophied and showed fewer protrusions called dendritic spines — suggesting weaker connections to surrounding nerve cells compared with healthy rats.

Once inside, researchers found that the antibodies zeroed in on their targets — viral antigens — and the radioisotopes destroyed nearby cancer cells without damaging surrounding healthy tissue.

Cancer cells rely on the healthy cells that surround them for sustenance.

Three new studies suggest ways to home in on cancer cells during treatment, leaving surrounding healthy tissue unharmed.

The resulting compound works by a unique mechanism of action unlike any drug currently used in the treatment of cancer, and it destroys replicating and nonreplicating malignant cells while minimizing damage to surrounding, healthy cells.

They believe the mutated gene causes cancer by triggering cytoskeleton malfunction, which allows the cancer cells to move more quickly than normal cells, essentially invading the surrounding healthy tissue.

The relatively small number of such cells in a youthful tissue is so small as to be harmless, but after decades of accumulation, the number becomes large enough that their abnormal metabolic state begins to pose a threat to surrounding, healthy tissues.

Cancer cells, through the protein - destroying enzyme, matrix metalloproteinase squeeze their way into healthy cells and destroy surrounding tissue.

Abnormal cells are created, forming tumors which invade surrounding healthy tissue.
