Converting blood cells to a stem cell state: an interview with Elias Zambidis, M.D., Ph.D.

The primitive stem cell state we created is called an “induced pluripotent stem cell” (iPSC). iPSC are a new, unique, and artificially-created type of stem cell that were first described in 2006 by a Japanese scientist named Shinya Yamanaka.

Sicor Biotech receives FDA approval for tbo-filgrastim to treat severe neutropenia

The U.S. Food and Drug Administration today approved Sicor Biotech's tbo-filgrastim to reduce the time certain patients receiving cancer chemotherapy experience severe neutropenia, a decrease in infection-fighting white blood cells called neutrophils.

Vitamin to the rescue in fight with ‘superbugs’

High doses of vitamin B3 may help fight against so called “superbugs” such as methicillin-resistant Staphylococcus aureus, show study results.

High doses of vitamin B3 stimulate CEBPE gene, enhance WBCs’ ability to combat staph infections

Cedars-Sinai researchers have found that a common vitamin may have the potential to provide a powerful weapon to fight certain "superbugs," antibiotic-resistant staph infections that health experts see as a threat to public health.

Nicotinamide may combat antibiotic-resistance staph infections

A new study suggests that nicotinamide, more commonly known as vitamin B3, may be able to combat some of the antibiotic-resistance staph infections that are increasingly common around the world, have killed thousands and can pose a significant threat to public health.

Tofacitinib shows promise in active ulcerative colitis

Tofacitinib can induce a clinical response in the majority of patients with moderate to severe, active ulcerative colitis, a placebo-controlled trial has shown.

Tofacitinib efficacy suggested for rheumatoid arthritis

The novel oral Janus kinase inhibitor tofacitinib significantly reduces signs and symptoms of rheumatoid arthritis, report two phase III trials published in TheNew England Journal of Medicine.

Neutrophils help kick off insulin resistance in obesity

Experts have found that neutrophils play an important role in initiating the chronic inflammation that characterizes obesity-induced insulin resistance.

Neutrophils play an unexpected role in mediating insulin resistance

Researchers at the University of California, San Diego School of Medicine say neutrophils, an abundant type of white blood cell typically tasked with attacking bacteria and other foreign invaders, also plays an unexpected role in mediating insulin resistance - the central characteristic of type 2 diabetes, which afflicts an estimated 26 million Americans.

Top-line results from Pfizer's tofacitinib Phase 3 study on moderate-to-severe active RA

Pfizer Inc. announced today top-line results from ORAL Start (A3921069), a Phase 3 study of the investigational agent tofacitinib, a novel, oral Janus kinase (JAK) inhibitor for the treatment of adults with moderate-to-severe active rheumatoid arthritis (RA).

UTMB researchers receives NIH grant to develop engineered lung tissue for biomedical studies

University of Texas Medical Branch at Galveston researchers have been awarded a two-year, $1.25 million National Institutes of Health grant to develop a method of custom-growing human lung tissue to make a three-dimensional model for biomedical studies.

Scientists decipher molecular causes of life-threatening candida fungal infections

With infectious diseases, it is often not the pathogen itself, but rather an excessive inflammatory immune responses death, for instance as a result of organ damage. On intensive care units, sepsis is the second-most common cause of death worldwide. In patients with a severely compromised immune system specially, life-threatening candida fungal infections represent a high risk of sepsis.

Human neutrophil peptide 1 effectively prevents HIV entry into cells in multiple ways

Human defensins, aptly named antimicrobial peptides, are made in immune system cells and epithelial cells (such as skin cells and cells that line the gut). One of these peptides, human neutrophil peptide 1, under certain circumstances hinders HIV infection, but exactly how it works remains unclear.

Insight into possible new approaches in vaccine development for blood-borne infections and HIV

White blood cells called neutrophils, which are the first line of defense against infection, play an unexpected role by boosting antibody production, according to research led by Mount Sinai School of Medicine. The findings suggest neutrophils have multiple roles within the immune system and function at levels previously unknown to the scientific community. The research, published in Nature Immunology, provides groundbreaking insight into possible new approaches in vaccine development for blood-borne infections and HIV.

Scientists capture high-quality images of immune cell trafficking in a beating heart

Blood flow to the heart often is interrupted during a heart attack or cardiac surgery. But when blood flow resumes, the heart may still falter. That's because collateral damage can occur as blood re-enters the heart, potentially slowing recovery and causing future cardiac troubles.

Thrombopoietin mimetic offers aplastic anemia hope

Eltrombopag significantly improves blood counts in some patients with refractory severe aplastic anemia, suggests research published in The New England Journal of Medicine.

Neonate blood-brain barrier more intact than adults following stroke

The ability for substances to pass through the blood-brain barrier is increased after adult stroke, but not after neonatal stroke, according to a new study the UCSF that will be published July 11 in the Journal of Neuroscience.

Study identifies possible new approach to defeat bacterial infections

Research led by St. Jude Children's Research Hospital scientists has identified a possible new approach to defeating bacterial infections by targeting an innate immune system component in a bid to invigorate the immune response.

Study illuminates key step in the journey of inflammation-producing immune cells

Like detectives seeking footprints and other clues on a television "whodunit," science can also benefit from analyzing the tracks of important players in the body's molecular landscape. Klaus Ley, M.D., a scientist at the La Jolla Institute for Allergy & Immunology, has done just that and illuminated a key step in the journey of inflammation-producing immune cells.

Blocking bombesin/GRP receptor improves survival in sepsis animal models

Septic shock is the most severe outcome associated with pathogen infection in the bloodstream. It is a life-threatening condition invariably leading to multiple organ dysfunctions. Currently, septic shock is one of the most frequent causes of death in intensive care units worldwide.
