Not sure if anyone is still on here but, does anyone have any expertise/experience with interrogating SNP/InDel in a mouse genome using a reference genome. We have an alignment and are using Integrated Genomics Viewer, but are having trouble figuring some stuff out.

I'm going to deactivate this account. I'm probably not going to be on Bluesky, but I've enjoyed a lot of scientific interactions on here, so my email (which can be found on my institution's website) is always open to hash out science stuff. Be well.

Does anyone know if there is an algorithm that can predict the likelihood a given epitopes will be generated upon antigen processing based on AA sequence? We're playing around with sites outside a known epitope, and are interested to know if they likely impact antigen processing.

Delighted to share our manuscript @ImmunityCP ! Thanks to the editorial team and reviewers for an outstanding process, to all the coauthors, and to Steve @Jamequistlab, who is an incredible mentor! Glad to take questions Quick thread 1/5 free access link authors.elsevier.com/c/1khA8…

I'm not qualified to assess the science described, but this excellent thread is exactly what science should be but rarely is.
A tumultuous 24-ish hours since our preprint was released yesterday. I mentioned that this was a fraught issue and I genuinely do understand that people have mixed feelings about the work. I wanted to take some time to respond to some of the concerns and comments that have 1/

It’s been a tough few weeks. My 10yo daughter was diagnosed with a very rare, aggressive cancer called interdigitating dendritic cell sarcoma (IDCS). I’m reaching out to identify clinicians/patients who have encountered pediatric IDCS, indeterminate dendritic cell histiocytosis or other (non-LCH) histiocytic sarcomas cases. I'm trying to understand non-surgical chemo and targeted therapy options, new pathology markers to better diagnose subtypes/treatments, and any data on progression in pediatric patients. Please feel free to share – I’m trying to cast a wide net due to the rarity of this condition and how little is known. People can contact me directly at my first name (as written in my profile) at octant.bio.

Our research is expanding beyond pregnancy. Excited to share our results by @Hilmill1113 (doi.org/10.1093/jimmun/vkae0…) investigating transplantation tolerance; and grateful to @J_Immunol, @ImmunologyAAI for streamlined review and support

Microbiologists are underrepresented in the microbiome field...helps explain why we focus largely on a handful of microbes (this is getting better), and why we can genetically modify very few microbiome members (good luck getting a grant to address that): nature.com/articles/s41564-0…

Everyone says “Today’s PhD students are so accomplished I wouldn’t have gotten in today” as if it’s a good thing. It’s not. There are amazing young scientists out there today. But grad admissions is ignoring wide swaths of them because it’s been infected with the same credentialist bullshit of faculty hiring and grants.
Pretty crazy after reviewing the applications of some Stanford PhD applicants and feel like they can graduate right away after the admission 😄

[To the three scientists still left here]: Interested in T cells and where they come from? Then now is the perfect opportunity to register for ThymUS (thymusmeeting.org). Don't miss out on what is shaping up to be a fantastic meting in gorgeous Kauai.

Ever wondered how gut microbes control immune responses at extra-intestinal locations? Here, #theonlylabever reports how a gut protozoan commensal microbe remotely shapes pulmonary immunity to exacerbate asthma and limit the dissemination of mycobacteria. @CellCellPress ⬇️(1/X)
