Researchers identify series of molecules involved in regeneration of damaged nerves

Researchers at Nagoya University have identified the series of molecules involved in the regeneration of damaged nerves in roundworm, showing that it largely overlaps with the signals used by the intrinsic removal system to take up and process dying cells.

Study findings shed light on fundamental feature of nerve repair

Through a study of roundworm nerve cells with severed axons, researchers at Nagoya University showed that a signaling cascade that normally functions in promoting the phagocytosis of apoptotic cells also acts in inducing axon regeneration.

Janssen’s Darzalex receives positive CHMP opinion for treating multiple myeloma patients

The Janssen Pharmaceutical Companies of Johnson & Johnson today announced that the Committee for Medicinal Products for Human Use of the European Medicines Agency has recommended broadening the existing marketing authorization for Darzalex® for use as frontline therapy.

New study shows how alcohol contributes to development of Alzheimer's disease

Research from the University of Illinois at Chicago has found that some of the genes affected by alcohol and inflammation are also implicated in processes that clear amyloid beta -- the protein that forms globs of plaques in the brain and which contributes to neuronal damage and the cognitive impairment associated with Alzheimer's disease.

Study provides insights into how immune cells kill bacteria with acid

The first line of immune defense against invading pathogens like bacteria are macrophages, immune cells that engulf every foreign object that crosses their way. After enclosing it in intracellular membrane vesicles, a process called phagocytosis, macrophages kill their prey with acid.

Small-molecule immunotherapeutics could steer immune defense against fungal pathogens

Fungal infections represent an increasing health crisis, especially for immune-deficient patients. American scientists now report in the journal Angewandte Chemie that specific help could be provided by small-molecule immunotherapeutics with novel mechanism of action.

Scientists reveal differences between human and murine microglia used in degenerative disease research

The results of a new research showed that many of the genes that are expressed by microglia are different between humans and mice, which are frequently used as animal models in research on Alzheimer's disease and other neurodegenerative disorders.

Dysfunctional microglia cells contribute to loss of synapses in Alzheimer's disease

Similar to other neurodegenerative disorders, Alzheimer's is a disease in which the cognitive abilities of afflicted persons continuously worsen.

Genetic manipulation of exosomes may offer new therapeutic approach to treating pancreatic cancer

Genetic manipulation of exosomes, virus-sized particles released by all cells, may offer a new therapeutic approach to treating pancreatic cancer, according to a study at The University of Texas MD Anderson Cancer Center.

Chronic sleep deprivation increases risk of neurological disorders

Recent research in mice indicates that destructive activity of cells in the brain is increased after sleep deprivation and may increase the risk of developing dementia, such as Alzheimer's disease.

Phagocytosis educates the immune system

Phagocytosis is a biological mechanism whereby specialized cells ingest and degrade old, dead, or damaged cells to prevent tissue damage due to their accumulation.

Study shows potential way to prevent formation of scar tissue around medical implants

Medical devices implanted in the body for drug delivery, sensing, or tissue regeneration usually come under fire from the host's immune system.

New discovery could lead to development of new cancer treatments

Macrophages are a type of white blood cell that can engulf and destroy cancer cells. A research group led by Professor MATOZAKI Takashi, Associate Professor MURATA Yoji, and YANAGITA Tadahiko, discovered that by using an antibody for a particular protein found on macrophages, the macrophage is activated, and cancer cells are effectively eliminated.

Janssen seeks to extend DARZALEX license to benefit more multiple myeloma patients

Janssen-Cilag International NV has announced the submission of a Type II variation application to the European Medicines Agency (EMA), seeking to broaden the existing marketing authorisation for the immunotherapy DARZALEX® (daratumumab) to include treatment of adult patients with relapsed multiple myeloma who have received at least one prior therapy. The expanded indication is based on daratumumab in combination with lenalidomide (an immmunomodulatory agent) and dexamethasone, or bortezomib (a PI) and dexamethasone.
