Fine-scale geospatial mapping of overweight and wasting (two components of the double burden of malnutrition) in 105 LMICs shows that overweight has increased from 5.2% in 2000 to 6.0% in children under 5 in 2017. Although overall wasting decreased over the same period, most countries are not on track to meet the World Health Organization’s Global Nutrition Target of <5% in over half of LMICs by 2025.

Serum Amyloid P is a humoral component with established roles in the response to bacterial infection and regulation of tissue remodeling. Here the authors provide evidence to a further crucial role of serum amyloid P in the context of fungal pathogen Aspergillus fumigatus.

Stravalaci et al. examined recognition of SARS-CoV-2 by human soluble innate pattern recognition receptor. They report that pentraxin 3 and mannose-binding protein recognize viral nucleoprotein and spike, respectively. Mannose-binding lectin has antiviral activity, and human genetic polymorphisms of MBL2 are associated with more severe COVID-19.

Systematic analysis from the Global Burden of Disease study reported that, despite global improvements from 1990 to 2021, dietary iron deficiency-associated disease burden remains high in women, children and residents in low socio-demographic index countries.

Along with a back-to-back published paper from Zielisnki and co. in this issue of Nature Immunology, this paper shows that NaCl affects CD8⁺ T cell function by counteracting the exhaustion of these cells in the tumor microenvironment.

Tumor-associated macrophages (TAMs) play multifaceted roles in establishing an immunosuppressive tumor microenvironment. Sica and colleagues find that macrophage-intrinsic complement signaling initiates a pathway leading to the induction of highly tumorigenic TAMs.

A modified fluctuation test applied to colorectal cancer cells shows that EGFR/BRAF inhibitor-induced persisters slowly proliferate and have an increased mutation rate. Error-prone DNA polymerases are identified as potential targets to avoid tumor recurrence following treatment with these drugs.

Interleukin-1 receptor 8 (IL-1R8), a negative regulator of the IL-1 family of cytokines, restrains the activity of natural killer (NK) cells, suggesting that IL-1R8 acts as a checkpoint regulator of NK cell activation and that its blockade may be of use in cancer therapy.

Current climate migration literature focuses on quantifying the link between climate drivers and migration, yet overlooks its broader and more complex interactions with mitigation, adaptation and climate impacts. This Perspective highlights key gaps and offers concrete solutions.

The authors of this Viewpoint discuss the protective activity of fenretinide on second breast cancer as a surrogate marker of primary prevention and the possibility of using this agent in young women bearing germlineBRCA-1 and BRCA-2mutations.

DOPA decarboxylase (DDC) in cerebrospinal fluid has great diagnostic potential for Lewy body disorders. Here, the authors report limited diagnostic potential of plasma DDC and a strong association with dopaminergic treatment.

Overexpression of c-MYC regulates tumor metabolism in pancreatic ductal adenocarcinoma (PDAC). Here the authors identify ELOVL6, a fatty acid elongase regulated by c-MYC, as a potential therapeutic target of PDAC.

Whole-genome sequence analysis identifies five independent risk loci for Lewy body dementia and demonstrates overlapping genetic architecture with Alzheimer’s and Parkinson’s diseases.

D1 receptor agonists bidirectionally regulate working memory capacity (WMC). Here, the authors show that low doses enhance WMC by activating cAMP/PKA in the striatum, whereas high doses impair it via prefrontal activation of striatal inhibitory neurons.

Modern neutrino experiments require precise tuning of energy response parameters, a task complicated by the parameters’ nonlinear behavior and strong correlations. The authors present neural density estimators using normalizing flows and transformers integrating them with Bayesian nested sampling to achieve near-zero systematic biases and uncertainties limited only by statistics, offering a flexible framework for particle physics applications

Hollunder et al. identify networks where deep brain stimulation reduces symptoms for Parkinson’s disease, Tourette’s syndrome, dystonia and obsessive-compulsive disorder. This revealed a fronto-rostral topography that segregates the frontal cortex.

Precision oncology relies on model systems that reflect the genomic heterogeneity of human cancers. Here the authors characterize a panel of 151 colorectal cancer cell lines with respect to genetic mutations, expression profiles and drug sensitivity to identify new therapeutic targets.

Large genome-wide meta-analysis of clinically diagnosed late-onset Alzheimer’s disease (LOAD) from 94,437 individuals identifies new LOAD risk loci and implicates Aβ formation, tau protein binding, immune response and lipid metabolism.

Prostate cancer is a heterogeneous disease, and many cases show somatic mutations of SPOP. Here, the authors show that a non-coding polymorphic regulatory element at 7p14.3 may predispose to SPOP mutant prostate cancer subclass through a hormone dependent DNA damage response.

PIN1 is a promising therapeutic target for cancer treatment. In this study, the authors identify a covalent inhibitor of PIN1 with anti-tumour and anti-metastatic properties thanks to PIN1 inactivation and to the release, after binding to PIN1, of a quinone-mimicking compound that elicits reactive oxygen generation and causes DNA damage.

The emergence of sub-clones that are resistant to targeted agents is a major therapeutic obstacle in oncology. Here, using colorectal cancer as a model system, the authors show that interfering with ancestral oncogenic events present in all subclones-like APC-WNT pathway alterations—can restrain the emergence of drug-resistant populations.

Inborn errors of the alternative NF-κB pathway in humans impair the development of AIRE-expressing medullary thymic epithelial cells, thereby underlying the production of autoantibodies against type I IFNs and predisposition to viral diseases

MRI could be used by clinicians as an effective tool to monitor patients with Crohn's disease. In this Review, Gionata Fiorino, Cristiana Bonifacio, Luca Balzarini, Alberto Malesci and Silvio Danese discuss the development of objective MRI-based scores that enable evaluation of the extent of intestinal damage. They also speculate on the generation of a new 'damage-driven' treatment paradigm—in which imaging is used to monitor intestinal damage and medication use is targeted to prevent the accumulation of further damage

Cancer therapy using systemically administrated 4-1BB-targeting antibodies is often associated with severe toxicity due to the nonspecific activation of autoreactive T cells. Here, the authors have developed a trimeric antibody targeting both 4-1BB and EGFR, which activates T cells effectively and shows negligible cytotoxicity.

This Primer by Wilson and colleagues summarizes the epidemiology, pathophysiology, diagnosis and treatment of neurological and psychiatric manifestations of COVID-19.

Lipid accumulation in the liver leads to nonalcoholic fatty liver disease (NAFLD) that is a risk factor for developing hepatocellular carcinoma (HCC). Here, the authors show that activation of the translation initiation factor eIF6 promotes lipid accumulation in the liver and targeting eIF6 in murine models reduces NAFLD and associated HCC.

Limits of AAV-mediated gene therapy include targeting dominant mutations and inducing long-term transgene expression. Here, the authors show that AAV-HITI results in efficient allele-independent integration of a donor DNA in both retina and liver providing therapeutic benefit in mouse models of either a genetic form of blindness or a lysosomal storage disease, respectively.

The membrane tetraspan protein MS4A4A is expressed on tissue-resident and tumor-associated macrophages. Locati and colleagues show that MS4A4A colocalizes with the β-glucan receptor dectin-1 to enhance cytokine and reactive oxygen species production and to enhance NK cell–mediated control of tumor metastasis.

Although progress in the coverage of routine measles vaccination in children in low- and middle-income countries was made during 2000–2019, many countries remain far from the goal of 80% coverage in all districts by 2019.

In the CheckMate 7FL trial, neoadjuvant nivolumab and chemotherapy in patients with newly diagnosed, high-risk estrogen receptor-positive breast cancer led to an increased pathological complete response rate compared with neoadjuvant chemotherapy alone, and this increase was associated with immune-related biomarkers and estrogen receptor expression.
