'Our study reveals that probiotic Lactobacillus reuteri (Lr) translocates to, colonizes, and persists within melanoma, where via its released dietary tryptophan catabolite I3A, it locally promotes interferon-γ-producing CD8 T cells, thereby bolstering ICI.'
'Using single i-cell transplantation from transgenic fluorescent donors to wild-type recipients, we find that these cells are pluripotent. Under physiological conditions, a single i-cell can differentiate into all somatic cell types and into gametes. The presence of embryonic-like, pluripotent cells throughout adult life facilitates their ability to grow indefinitely in a plant-like fashion.'

'Now, Takahashi et al. showed that the inheritance of acquired methylation states is not restricted to highly repetitive transposable elements only but can also occur in promoter-associated CpG islands (CGIs) of endogenous genes.'
'Many art experts say Lichtenstein’s use of source comics was fair appropriation. Yet Eisman, 96, who lives in New Jersey, tells The Washington Post by email: “I’d say it’s theft.” He hopes people will watch the documentary and see it as evenhanded, intended to represent both sides with the aim to let “the viewers make up their own minds and not just leave it to the so-called experts.”

'In this Primer, we outline the current understanding of #chikungunya fever based on research in patients and animal models, which have provided considerable insights into the complex spectrum of disease manifestations and the mediators of arthritic immunopathology.'

"Understanding the mechanisms that maintain the endothelial barrier in the context of pathological stressors is the first step toward the development of new therapeutic approaches for retinopathies."
T2 Phage by Madalena Parreira, a drawing for a piece I did on the Hershey-Chase experiments when I was at J Exp Med (for the short-lived JEM blog).
"Thus, we performed a comprehensive screen of TE-chimeric transcripts across 10,357 tumors, 675 cancer cell lines and 11,686 Genotype-Tissue Expression (GTEx) adult tissues, and evaluated these TE-chimeric candidates for tumor specificity, antigenic potential, proteomic validation, HLA presentation and membrane presence."

"These differences in expression necessarily limit the usefulness of these systems in identifying and understanding the more subtle roles played by ACE2 in the development and resolution of COVID-19. To overcome these limitations, we have developed two mouse lines in which the ACE2 locus has been humanized by syntenic replacement."

RIP Avrion Mitchison.
"Av initiated a series of experiments that collectively provided the conceptual framework of much of today’s understanding of immune rejection, tolerance and T–B cell co-operation."
'Here, we developed a memory-guided behavioral task that mice perform reliably in the head-fixed setting for months, and performed anatomical tracing, neural dynamic recordings, and optogenetic perturbations to characterize the role of these intervening circuits in memory consolidation.'

Some of my favorite cover illustrations by Madalena were not selected by editors - like this one for Ilana Gabanyi & @mucida's 2016 paper "Neuro-immune Interactions Drive Tissue Programming in Intestinal Macrophages"
Strong opening:
"Like most forms of corruption, it began with men in suits."
"The multiple communication modalities characterized here reveal how nociceptors and DCs form a neuroimmune unit that integrates the nociceptors’ rapid responsiveness and finely honed ability to sense and respond to noxious stimuli with the DCs’ ability to coordinate innate and adaptive immune responses."
"Collectively, our findings demonstrate HCMV reactivation in senescent cells, which CD4 CTLs can directly eliminate through the recognition of the HCMV-gB antigen."
If you're in London:
"Berthe Morisot, extraordinarily a footnote in Impressionist history until a decade ago, arrives at London’s Dulwich Picture Gallery for her first UK exhibition in 70 years. It’s a wonderfully sympathetic, intelligent, enlightening show, placing Morisot at the heart of French painting while allowing her individuality to shine."

I've worked on all of science, from B cells to T cells.
