Negative Strand Virus (NSV) Conference 2022

The Negative Strand Virus conference was held in Braga, Portugal last week. Cindy, Maddy, and I made the trip (first in-person conference since before COVID!).

We met colleagues and collaborators whom we’ve never seen in person before. It was a fabulous week of virology & socializing!

See more photos from our trip to Portugal in the gallery!

Maddy won the poster prize for the “Damaging and Spreading” section!

Data was discussed!

Cooling off with sangria with the WashU Crew!

Posters were presented!

Fun was also had, despite the travel issues!

Rotations for 2022-23 year

If you are an incoming PhD student in either the IDM or PMI graduate programs and are interested in rotating in our lab, please reach out to me. Rotation slots tend to be on a first-come first-serve basis, and if I have more interested students than available slots, I will interview and select from there.

Summer conferences

Here’s an update on where you can find us this summer!

Kaleigh Connors (PhD student) will present a poster entitled: In vitro and ex vivo brain culture models uncover the direct effect of Rift Valley fever virus infection on primary neurons" at the American Society for Virology's 41st Annual Meeting, which is being held at the Monona Terrace in Madison, WI, July 16 – 20, 2022.

A few Hartman Lab members will be attending the 2022 Negative Strand Virus Conference in Braga, Portugal in June:

Madeline Schwarz (PhD student) will present her work entitled: “Development of a novel rodent model of Rift Valley fever ocular disease.”

Cynthia McMillen, PhD will present her recent work: “Therapeutic and Prophylactic Delivery of Potent Neutralizing Human Monoclonal Antibodies Prevents Vertical Transmission of RVFV in Sprague Dawley Rats” 

Amy Hartman, PhD will also present: “Lrp1 mediates cellular infection by diverse bunyaviruses.”

Hope to see everyone in person again soon!

Two new preprints are up on BioRXIV

2022 has been busy, hence I haven’t posted an update in a while….but here is a free picture of Nacho!

And two manuscripts we’ve been working hard on!!

Lrp1: New host factor for Rift Valley fever virus infection

A major study of ours was just published in Cell, with a fabulous Leading Edge review written about the study. We had no idea that Cell was soliciting a review, so this was a complete surprise!

You can read my synopsis of our work and how it came about in my twitter thread here.

This was such an interesting journey from meeting Dr. Gaya Amarasinghe at NSV2018 to publication! Lots of individuals contributed over the years at several institutions and I’m super proud of this work. I’m also glad we can talk about it! The Lrp1 story has turned into a major effort in our lab and has cross-cutting implications for all of our projects.

New Pre-Print is posted

We have a new pre-print on BioRXIV. This is the companion paper to the EEEV paper we published earlier this year. Huge collaborative effort between Klimstra, Reed, and Hartman labs in the Pitt CVR.

“Long-term persistence of viral RNA and inflammation in the CNS of macaques exposed to aerosolized Venezuelan equine encephalitis virus,”
