How to design a cancer-killing virus
One new way to treat individuals with cancer that is being developed is the use of viruses that infect and kill cancer cells while leaving normal cells unharmed. view more (2007-10-26)
Baffling the body into accepting transplants
An unexpected discovery made by a Sydney scientist has potential to alter the body's response to anything it perceives as not 'self', such as a tissue or organ transplant. view more (2009-01-21)
Immune cells contribute to the development of Parkinson's disease
Parkinson disease is a neurodegenerative disorder that impairs movement, balance, speech, and other functions. It is characterized by the loss of nerves in the brain that produce a substance known as dopamine. view more (2008-12-23)
Scientists can now differentiate between healthy cells and cancer cells
One of the current handicaps of cancer treatments is the difficulty of aiming these treatments at destroying malignant cells without killing healthy cells in the process. view more (2009-01-06)
HIV infection requires an accomplice: B cells with special protein direct HIV to T cells
HIV infection of T cells requires activation of a molecule on the surface of B cells, a finding that reveals yet another pathway the virus uses in its insidious attack on the immune system. view more (2006-08-14)
Scientists identify cells responsible for relapse after treatment in common childhood cancer
Approximately 20% of children with ALL will experience a relapse of their disease following treatment. Of these, most will never be cured. view more (2007-03-29)
Ovarian cancer stem cells identified, characterized
Researchers at Yale School of Medicine have identified, characterized and cloned ovarian cancer stem cells and have shown that these stem cells may be the source of ovarian cancer's recurrence and its resistance to chemotherapy. view more (2008-04-18)
Scientists discover stage at which an embryonic cell is fated to become a stem cell
Cambridge scientists have discovered the stage at which some of the cells of a fertilised mammalian egg are fated to develop into stem cells and why this occurs. view more (2007-01-11)
DFG remains skeptical of the cloning of human cells
According to a paper published in the journal Stem Cells, an American group has succeeded in inserting cell nuclei from human skin cells into human enucleated oocytes and to stimulate these new cells to undergo cell division in the laboratory. view more (2008-01-23)
A link between mitochondria and tumor formation in stem cells
Researchers report on a previously unknown relationship between stem cell potency and the metabolic rate of their mitochondria -a cell's energy makers. Stem cells with more active mitochondria also have a greater capacity to differentiate and are more likely to form tumors. view more (2008-10-13)
Well-armed immune cells help long-term nonprogressors contain HIV
To help develop an effective HIV vaccine, researchers are trying to better understand how the immune systems of a small minority of HIV-infected people known as long-term non-progressors (LTNPs) contain the virus naturally. view more (2008-12-05)
Drawing a crowd: Understanding the signals that bring inflammatory cells into the lung
Understanding the connection between influx of immune cells into the lung and acute lung injury is essential, since lung damage tends to occur secondary to increased lung inflammation. view more (2006-02-17)
Potential autoimmunity-inducing cells found in healthy adults
It's not just patients with autoimmune diseases like lupus and rheumatoid arthritis (RA) that have self-attacking immune cells-healthy people have them too, according to a new report in the Journal of Experimental Medicine. view more (2008-12-22)
Cell removal technique could lead to cheaper drugs
Researchers at the University of Edinburgh have pioneered a simple way to remove dead cells from cell cultures used to make protein-based drugs, which are increasingly prescribed to treat a range of illnesses. view more (2008-08-27)
Deakin University research finds rogue cells that could cause spread of breast cancer
Stephanie Lebret completed the study for her PhD at Deakin's Centre for Cellular and Molecular Biology under the supervision of Associate Professor Leigh Ackland. view more (2007-06-14)
Donor T cells change the fate of stem cells in transplantation
When a transplant patient suffers complications such as graft rejection or graft-versus-host disease, physicians attempt to stop the body's immune response by targeting a patient's T cells. view more (2006-07-13)
Cellular antacids give vaccines a boost
Scientists in Italy have found that a drug that blocks acid buildup inside cells revs up the immune response to vaccines. view more (2005-09-12)
Drawing a crowd: How progenitor cells are recruited to tumor blood vessels from the bone marrow
Cells within the bone marrow (progenitor cells) that express a protein called CD34 have been shown to leave the marrow and travel to sites of tissue injury to mediate repair. view more (2006-02-24)
Combination therapy with a monocloncal antibody and a vaccine leads to tumor rejection
Effector T cells (Teff cells) are involved in activating and directing other immune cells, while regulatory T cells (Tregs) act to curb the over-aggressive responses of the T cell population. view more (2006-06-16)
A step forward in stem cell research
According to research published today, investigators from Memorial Sloan-Kettering Cancer Center (MSKCC) have used new techniques in the laboratory that allowed them for the first time to derive unlimited numbers of purified mesenchymal precursor cells from human embryonic stem cells (HESCs). view more (2005-06-27)
