Nature Medicine is the premier journal for biomedical research. Respected internationally for the quality of its papers on areas ranging from infectious disease to cancer and neurodegeneration, Nature Medicine aims to bridge the gap between basic research



 












Obesity: will withaferin win the war?

2016-09-07

A new study shows that withaferin A, a steroidal lactone isolated from Withania somnifera, can exert profound metabolic benefits in mice, including body-weight loss, reduced hepatic steatosis and improved glucose control.



Dysregulated exocytosis of angiopoietin-2 drives cerebral cavernous malformation

2016-09-07

A new study has proposed a mechanism for the pathogenesis of cerebral cavernous malformation (CCM) that links endothelial CCM3 deficiency to increased secretion of the vascular destabilizing protein angiopoietin-2 (ANGPT2).



Friendly fire: anti-cytokine antibodies elicited by microbes

2016-09-07

A recent study suggests that exposure to the mold Aspergillus induces the production of antibodies that neutralize interferon-γ (IFN-γ), which increases the risk of mycobacterial disease.



Therapeutic targeting of splicing in cancer

2016-09-07

Patterns of splicing are frequently altered in cancer, and genes that encode splicing regulatory factors are often mutated. Thus, recent strategies have emerged to target splicing alterations in cancer, which are reviewed here.



A genome-editing strategy to treat β-hemoglobinopathies that recapitulates a mutation associated with a benign genetic condition

2016-08-15

CRISPR–Cas9-mediated insertion of a naturally occurring benign mutation in blood cell progenitors from patients with sickle cell disease increases fetal hemoglobin expression to levels sufficient to ameliorate the pathological morphology observed in erythrocytes differentiated from these cells.



Low-dose interleukin-2 treatment selectively modulates CD4+ T cell subsets in patients with systemic lupus erythematosus

2016-08-08

Low-dose IL-2 treatment alters the abundance of regulatory T cells, IL-17-producing T cells and follicular helper T cells, but not of T helper type 1 and 2 cells, in patients with SLE.



Identification of a major epitope by anti-interferon-γ autoantibodies in patients with mycobacterial disease

2016-08-15

Cheng-Lung Ku and colleagues report that anti-interferon (IFN)-γ autoantibodies in patients with disseminated mycobacterial infections recognize the C-terminus of IFN-γ, and suggest that autoantibodies may arise by molecular mimicry. The authors propose a therapeutic strategy to treat patients using a modified IFN-γ that escapes neutralization by autoantibodies.



NOX4-dependent fatty acid oxidation promotes NLRP3 inflammasome activation in macrophages

2016-07-25

In macrophages, Nox4 drives fatty acid metabolism, which in turn activates the NLRP3 inflammasome. This pathway can be pharmacologically targeted in vivo by inhibiting Nox4 to reduce S. pneumoniae infection in mice.



An asthma-associated IL4R variant exacerbates airway inflammation by promoting conversion of regulatory T cells to TH17-like cells

2016-08-01

An IL4R polymorphism associated with severe asthma drives conversion of regulatory T cells to TH17 cells; this can be inhibited by neutralizing interleukin-6.



Withaferin A is a leptin sensitizer with strong antidiabetic properties in mice

2016-08-01

Withaferin A is a naturally occurring compound that has potent antidiabetic and anti-obesity properties in mice.



Endothelial exocytosis of angiopoietin-2 resulting from CCM3 deficiency contributes to cerebral cavernous malformation

2016-08-22

In a mouse model of cerebral cavernous malformation, deletion of the gene PDCD10 leads to vascular defects in the central nervous system as a result of increased UNC13-mediated exocytosis and secretion of angiopoietin-2 by endothelial cells.



Defective proviruses rapidly accumulate during acute HIV-1 infection

2016-08-08

Bruner et al. report that defective HIV-1 proviruses predominate in early infection, even when antiretroviral therapy is initiated in the first months after infection. The results highlight challenges in estimating the reservoir of intact, replication-competent virus that may influence cure strategies.



3K3A–activated protein C stimulates postischemic neuronal repair by human neural stem cells in mice

2016-08-22

The ability of transplanted neural stem cells to ameliorate neuropathological and behavioral phenotypes after experimental stroke in mice is enhanced by co-treatment with 3K3A-APC, which acts to stimulate neuronal differentiation and functional integration within the host circuitry.



Loss of cohesin complex components STAG2 or STAG3 confers resistance to BRAF inhibition in melanoma

2016-08-08

Mutation or downregulation of cohesin components confer ERK reactivation and resistance to BRAF or MEK inhibitors in melanoma cells expressing BRAF or NRAS activating mutations.
