Excited to start my research group @uniheidelberg.bsky.social at the @ciid-heidelberg.bsky.social where we’ll be studying how inflammatory responses shape viral disease outcome and elicit epigenetic memory. Don’t hesitate to reach out if you want to know more or collaborate! lercherlab.github.io

Could a cross-organ warning system be a defining factor in how the brain combats arthropod-borne neurotropic viruses?

The main function of the TCA cycle is to feed electrons into the respiratory chain. ..wait, what!? It also clears excess citrate, because otherwise you get severe kidney damage? Great example that textbooks aren’t always the full story by Abby, @juliabrunner.bsky.social and @lydiafinley.bsky.social

A CLOCK-targeting lncRNA induces trained immunity against tuberculosis
Yu et al. discover that TRCR1, a tuberculosis resister-derived exosomal lncRNA, induces trained immunity via CLOCK-mediated epigenetic reprogramming. They show that mycobacterial protein MPT53 prompts...

Antiviral innate immune memory in alveolar macrophages following SARS-CoV-2 infection ameliorates secondary influenza A virus disease
The therapeutic potential of antigen-independent innate immune memory (IIM) is of particular relevance in the context of respiratory viruses with pandemic potential. Lercher et al. find that antiviral...

Location, infection history, antigen persistence shape the phenotype of tissue-resident T cells (Trm), challenging the idea of a universal framework for Trm identity across organs and diseases. High/low antigen immunogenicity may add another layer... @cp-immunity.bsky.social tinyurl.com/49dkc3j7

A commensal bacterium triggers systemic antibody responses via skin lymphoid structures and can be engineered as a topical vaccine – great therapeutic potential! Two studies in @nature.com.web.brid.gy by the Fischbach and Belkaid labs tinyurl.com/5yahn47t tinyurl.com/4n4btxap

If you are rather an auditory person than a reading person – TWIV discussed our recent paper on antiviral innate immune memory in sequential respiratory viral infections. Paper review starts at 37:00, more general discussion and broader implications at 1:10:00. open.spotify.com/episode/777w...

How do past viral infections influence future viral diseases? We found that SARS-CoV-2 recovery protected from severe influenza A virus disease. But how come? There seemed to be some antigen-independent immunological memory going on.. Paper at Immunity: www.sciencedirect.com/science/arti...

Chronic autoimmunity rewires metabolism in progenitors, correlating with innate immune memory formation in macrophages that increases antibacterial activity but might also aggravate autoimmune diseases? shorturl.at/SZ1Ww #CellStemCell

Curious how commonly circulating respiratory viruses affect respective disease? Past SARS2 infection ameliorates disease caused by secondary influenza virus via innate immune memory in airway-resident macrophages. @biorxivpreprint.bsky.social link below. www.biorxiv.org/content/10.1...
