A mutation on the surface of human red blood cells provides protection against malaria caused by Plasmodium vivax. Research found that the parasite binds less easily to cells expressing a specific variant of the Duffy blood group antigen, reducing the risk of infection.
Scientists at Brigham and Women's Hospital create a platform approach that incorporates homing receptors onto cell surfaces to target specific tissues. This enables more efficient cell-based therapies by increasing the concentration of cells at target locations in the body.
A research team led by Bradley Davidson discovered that specialized structures in sea squirt cells, called invadopodia, may help cancer cells evade elimination processes. In contrast to cancer cells, sea squirt cells use these structures to pick up chemical signals for development, not invasion.
Researchers discovered that many proteins are required for maximum toxicity of ricin and PE, with differing requirements at multiple levels. Understanding toxin trafficking may lead to designing treatments targeting these toxins and potential synergistic therapies.
Researchers at Duke University Medical Center have discovered a possible new treatment for idiopathic pulmonary fibrosis (IPF) by targeting the invasive type of cell that leads to lung fibrosis. By reducing the production of hyaluronan and blocking its receptor, they were able to prevent fibrosis in living mice.
A study published in Immunity describes a mechanism by which an infected cell can alert neighboring uninfected cells, leading to amplified inflammation and enhanced immunity. This 'cell-to-cell communication' strategy enables the host to circumvent immunosuppressive bacterial activity and defeat invaders.
Preliminary research published in Gut suggests that plantain and broccoli fibers may prevent the translocation of E. coli across M-cells, a key stage in Crohn's disease development. The study found that plantain and broccoli fibers reduced E. coli translocation by 45-82%, while leek and apple fibers had no effect.
Researchers from the University of Montreal have identified an enzyme called NOX2 that generates highly reactive oxygen derivatives to activate defense genes and molecules against viral invasions. The study reveals how these free radicals serve a critical role in mounting an immune response to viral infections.
Researchers found that ALDH-positive tumor cells have a worse prognosis and are more likely to proliferate and invade compared to ALDH-negative cells. ALDH-positive cells were detected in 90% of primary surgical specimens and were associated with shorter overall survival.
The SRC-3 gene enhances breast cancer growth and invasion by activating cell motility, allowing cancer cells to invade surrounding tissue. Researchers found that the gene enables an alternative form of its coactivator protein to function at the cell membrane, leading to increased cancer spread.
Researchers at LSUHSC have identified miR-27b as a major player in the development of invasive breast cancer, found to stimulate cell growth and invasion. Meanwhile, ST14 gene suppresses tumor cell growth and may serve as an early detection marker for breast cancer.
Researchers have identified MEK4 as a key player in promoting cell invasion in prostate cancer. Genistein, a dietary compound, inhibits MEK4 kinase activity, suggesting potential therapeutic applications for prostate cancer treatment.
LSUHSC researchers discovered that excessive IQGAP1 production weakens cell-to-cell contacts, promoting cell migration and invasion. The study provides insights into the prolonged activated state of Cdc42, a key protein involved in cancer spread.
FAK coordinates movement of migrating cancer cells by balancing the number of invadopodia that create a path for migration and the number of focal adhesions that hold the cell back. In its absence, breast cancer cells sprout extra invadopodia and form large, sticky focal adhesions.
A new species of microsporidia has been discovered in a roundworm, providing a powerful system to study these mysterious microbes and develop new drugs. The discovery is particularly exciting as it offers a unique opportunity to identify new treatments for human microsporidian infections.
Researchers confirm that bacteria responsible for UTIs are entrenched inside human bladder cells, contradicting previous models. The finding confirms the importance of fully understanding bacterial behavior in the bladder to develop better diagnoses and treatments.
Researchers at Harvard Medical School have discovered a new type of programmed cell death called entosis, where cells bore into their neighbors and died. This process, known as entosis, was found to be more common in cancerous cells than previously thought, and its role in tumor progression is still unclear.
Biologists used simple equations to describe the motion of Listeria monocytogenes, reproducing all observed shapes with just two variables. The equations can help identify bacterial mutants and rule out mechanisms driving the motion.
A new task for IgG has been discovered, helping cells capture germs and dispose of them. The antibody aids in the formation of phagolysosomes that kill off invading microbes.
Researchers at Vanderbilt-Ingram Cancer Center have identified a crucial link between the CXCR4 receptor and the invasion of glioblastoma, a type of aggressive brain tumor. By inhibiting this receptor, experts hope to develop new treatments to prevent cancerous cells from spreading to other organs.
Scientists have identified a new mechanism by which Listeria invades non-phagocytic cells, revealing similarities between phagocytosis and endocytosis. Researchers found that Listeria uses endocytosis to transport tagged proteins inside the cell.
A team of researchers has identified an intermediate stage in virus-cell fusion that lasts several minutes, providing a potential window of opportunity for drug development. This discovery may allow existing drugs to be re-evaluated and fine-tuned to target this critical point in the viral entry process.
Researchers have watched infectious prion proteins invade and move within brain cells, shedding light on transmissible spongiform encephalopathies (TSE) diseases. The findings may lead to ways to prevent or minimize their effects.
A Rutgers-Newark scientist has found that mosquitoes may carry a lethal parasite called B. algerae, which can invade human muscle tissue and cause death. The parasite is typically found in the tissues of mosquitoes and can be transmitted to humans through mosquito bites.
E. coli bacteria undergo four distinct developmental stages during UTIs, including a quiescent state that may create reservoirs for recurrent infections. Researchers hope to use these stages as guides for new drug development.
Researchers found endostatin treatment reduced invasive head and neck cancer cells by half and their migratory capabilities by one-quarter. The study suggests an implanted drug delivery system could provide sustained therapeutic drug levels directly to tumors.
