Come see Mark Maynes today if you are at SfN Chicago! Poster C45. He will present spectral flow cytometric analysis of discrete effector immune cell types in experimental AD. Analysis of brain atrophy with preclinical MRI will be discussed as well. @markmaynes #SfN24

Dear diary- Today I went to the glia social at #Sfn2024 and met the one and only Shane Liddelow 🍊 . I ended up at a pitch competition talking about microglia presenting antigens to CD8 T cells and had one of the most memorable nights ever! Thanks boss for the support Aaron Johnson

Come see second year biochemistry grad student, Javonte Thelwell, present his work on the impact of MHC Class I molecules expressed by vascular endothelial cells on antiviral CD8 T cell infiltration of brain parenchyma. This morning at the Dementia nanosymposium!

And that’s a wrap for the Society for Neuroscience (SfN) Conference in Chicago this week! Our projects included neurodegeneration, neuroinflammation, skull bone marrow immunology, and antigen presentation by vasculature and microglia. Marina Seady asmahassani🦠🧠 Mark Maynes

Last day of Shanon’s rotation! Thank you Shanon Rego for all the help and valuable insights. It was a pleasure working with you. A suggestion for your next rotation: a map of the Mayo Arizona campus so we don’t lose you forever 😅 Até a próxima!

4 generations of scientists at Autumn Immunology Conference. Larry trained Aaron. Aaron trained me. I am now training others, who will go on to train as well. Aaron Johnson

A fun weekend to have our lab’s Dr Asma Hassani and Dr Marina Seady present at AIC in Chicago. Also great to catch up with old friends, hang out with my PhD mentor Larry Pease, and enjoy my immunology grandchildren (Larry’s great grandchildren) from Dr Robin Orozco’s lab

Fernanda Torres makes history as the first Brazilian to win the Best Actress: Drama category at the #GoldenGlobes  Her own mother, Fernanda Montenegro was previously nominated in the same category in 1999.

Many thanks to the Journal of Nutritional Biochemistry for highlighting my paper! :)

Brazil snags the Oscar for Best International Feature Film. Congratulations to the cast and crew of I'M STILL HERE! 🇧🇷 #Oscars

Hey if anyone is at AAI #IMMUNOLOGY2025 then come check out my talk on pericyte antigen presentation at 10:45 am.

Johnson Lab schedule for #IMMUNOLOGY2025 🌺 If you want to know more about CD8 T cells in the brain, NVU cell types as antigen presenting cells and more come check our oral and poster presentations! Aaron Johnson

I’ll be at the poster from 2:15 to 3:30! Excited to hear your thoughts on microglia as antigen presenting cell later today :)

Sharing Dr Marina Seady’s comprehensive review published in Trends in Neuroscience regarding CD8 T cell mediated blood-brain barrier disruption. Great job Marina! Marina Seady lnkd.in/gPZsTA4j

Drawing attention to our senior immunology student Mark Maynes who published his MRI and spectral flow cytometry methods to measure neuroinflammation and neurodegeneration in dementia models. Nice job Mark! Mark Maynes sciencedirect.com/science/articl…
