University of Copenhagen researchers discover Achilles heel of bacteria

Drug resistant bacteria are fast becoming one of the big worries of the 21 century. Now researchers at the University of Copenhagen have discovered a previously unknown weakness; an "Achilles heel", of bacteria. Their discovery, a crucial step in bacteria's energy metabolism, may be the first step in developing an entirely novel form of antibiotics

Research sheds new light on genetic relationship between ASD and ASD-related traits in wider population

New light has been shed on the genetic relationship between autistic spectrum disorders (ASD) and ASD-related traits in the wider population, by a team of international researchers including academics from the University of Bristol, the Broad Institute of Harvard and MIT, and Massachusetts General Hospital.

Four key genes govern growth, multiplication of blood stem cells

An important element in getting blood stem cells to multiply outside the body is to understand which of the approximately 20,000 genes in the human body control their growth. Now a research team at Lund University in Sweden has studied close to 15,000 of these genes alongside each other.

Researchers use DNA sequencing technology to identify gene variants that affect susceptibility to SLE

Demonstrating the potential of precision medicine, an international study based at UT Southwestern Medical Center used next-generation DNA sequencing technology to identify more than 1,000 gene variants that affect susceptibility to systemic lupus erythematosus (SLE).

Researchers disprove previously assumed behavior of macrophage immune cells

What happens when macrophage immune cells are activated in the course of an inflammation to combat pathogens such as bacteria or viruses? Researchers of the Luxembourg Centre for Systems Biomedicine of the University of Luxembourg pursued this very question. The researchers discovered that the immune cells behave differently from what was previously assumed. Their metabolism upholds the production of antimicrobial substances and fatty acids during activation. In this way, they deliver important resources for the immune responses they trigger.

Advanced genomic sequencing tracks deadly blood infection in cancer patients

The Translational Genomics Research Institute, working with international investigators, have discovered the source of a potential deadly blood infection in more than 50 South American cancer patients.

KORs could be potential drug target for treatment of addiction, anxiety disorders

University of North Carolina researchers uncovered a cellular mechanism by which kappa opioid receptors (KOR) drive anxiety. These proteins inhibit the release of the neurotransmitter glutamate in a part of the brain that regulates emotion.

Study shows aging affects adaptive immune responses

Today at the 45th Annual Meeting & Exhibition of the American Association for Dental Research, researcher Jeffrey Ebersole, University of Kentucky, Lexington, USA, will present a study titled "Systemic Antibody Responses to Oral Bacteria with Aging." The AADR Annual Meeting is being held in conjunction with the 40th Annual Meeting of the Canadian Association for Dental Research.

Combined loss of XPO1, BCL11A and REL linked to 2p15p16.1 microdeletion syndrome

Individuals with 2p15p16.1 microdeletion syndrome present with intellectual disability, microcephaly, delayed growth, dysmorphic craniofacial features, and digital abnormalities.

Aging-associated changes begin earlier than expected in human brain

A new study published in Physiological Genomics suggests that the brain shows signs of aging earlier than old age. The study found that the microglia cells—the immune cells of the brain—in middle-aged mice already showed altered activity seen in microglia from older mice.

New molecular probe can detect different amyloid deposits in human tissues

A team of scientists at Sweden's Linköping University have developed a molecular probe that can detect an array of different amyloid deposits in several human tissues. This new probe is extremely sensitive and was used at very low concentrations to correctly identify every positive amyloidosis sample when compared to the traditional clinical tests.

IUPUI investigators use stem cells to identify potential therapies to prevent glaucoma

Using stem cells derived from human skin cells, researchers led by Jason Meyer, assistant professor of biology, along with graduate student Sarah Ohlemacher of the School of Science at Indiana University-Purdue University Indianapolis, have successfully demonstrated the ability to turn stem cells into retinal ganglion cells (RGCs), the neurons that conduct visual information from the eye to the brain.

Researchers describe generation of plasma cell-specific antibody from immunized lampreys

Antibody-secreting plasma cells arise from B cell precursors and are essential for adaptive immune responses against invading pathogens. Plasma cell dysfunction is associated with autoimmune and neoplastic disorders, including multiple myeloma.

Researchers elucidate mechanisms underlying impaired ciliogenesis in PKD

In an article published online ahead of print on Feb. 19, 2015 in the Journal of Biological Chemistry, investigators at the Medical University of South Carolina and the Ralph H. Johnson VA Medical Center report findings from in vitro and in vivo studies that elucidate the mechanisms underlying the impaired ciliogenesis and abnormal kidney development characteristic of polycystic kidney disease (PKD).
