Decoding sex differences in human immunity through systems immunology Abstract. Immune function varies widely across humans. Biological sex is a key factor underlying human immune variability, with men presenting with more se

I'm thrilled to share that my first co-authored review, "Decoding sex differences in human immunity through systems immunology," on Oxford Open Immunology! I'm so grateful for the opportunity to have worked with Tianze Cao and @consigliocr.bsky.social on this. doi.org/10.1093/oxfi...

Thanks! Great resource anyway.

Stimulating immune cells in vitro is a common experimental lab model. We profiled 150K blood immune cells treated with 11 different stimuli to compare the effects. The data are freely available for researchers. See the preprint for our findings and to access the data 🧪 doi.org/10.1101/2025...

Very interesting work! Out of curiosity, what was the sex/gender of the individuals? Was it addressed in any way?

Join us for this exciting webinar tomorrow, 24th June 2025 at 14h00 CEST!

@resabut.bsky.social PhD student in my #SystemsImmunology will be speaking ;)

Integrated analysis of the complete sequence of a macaque genome | Nature The crab-eating macaques (Macaca fascicularis) and rhesus macaques (Macaca mulatta) are pivotal in biomedical and evolutionary research1–3. However, their genomic complexity and interspecies genetic differences remain unclear4. Here, we present a complete genome assembly of a crab-eating macaque, revealing 46% fewer segmental duplications and 3.83 times longer centromeres than those of humans5,6. We also characterize 93 large-scale genomic differences between macaques and humans at a single-base-pair resolution, highlighting their impact on gene regulation in primate evolution. Using ten long-read macaque genomes, hundreds of short-read macaque genomes and full-length transcriptome data, we identified roughly 2 Mbp of fixed-genetic variants, roughly 240 Mbp of complex loci, 16.76 Mbp genetic differentiation regions and 110 alternative splice events, potentially associated with various phenotypic differences between the two macaque species. In summary, the integrated genetic analys

Independent effects of testosterone, estradiol, and sex chromosomes on gene expression in immune cells of trans- and cisgender individuals The origins of sex differences in human disease are elusive, in part because of difficulties in separating the effects of sex hormones and sex chromosomes. To separate these variables, we examined gen...
