Lindsay defending her PhD!

She is Kenough

This was an exciting month with Lindsay Sidak-Loftis successfully defending her dissertation! (titled “Unraveling arthropod immunity: Investigating the unfolded protein response as an initiator of the immune deficiency pathway in Ixodes scapularis ticks”)! Lindsay is the first PhD student out of the Shaw lab and we are super proud of all of her accomplishments!! Congrats, Lindsay!

We also had some conference travel here in the PNW!

  • Kaylee Vosbigian presented a poster at the CVM Research Symposium on titled “Pathogen persistence in ticks is supported by ATF6 and Nrf2 gene regulation”

  • Kaylee Vosbigian and Sarah Wright traveled to Portland, OR on for the American Society of Microbiology Northwestern Branch Meeting to present posters on their research.

October 2023

This has been a busy Fall semester with lots of conference presentations and awards!

Shaw lab Halloween party!

  • Elis Fisk traveled to Chicago, IL for the annual ACVP meeting to present his poster titled “Forbidden snack: C57BL/6 mice as a model for acquired resistance to Ixodes scapularis

  • Elis was also the recipient of the 2023 Davis-Thompson Foundation Pathology Trainee Scholarship Award, which goes to trainees who have demonstrated superior scholarship, exceptional diagnostic skills, mentorship, leadership, in addition to talent and enthusiasm for teaching - congrats, Elis!

  • Kaylee Vosbigian was the recipient of the 2023 Excellence in Research Award, which celebrates students with exceptional contributions to the scientific community and who have prioritized mentorship and collaboration within VMP - congrats, Kaylee!

  • Dana traveled to the University of Nebraska Medical Center on Oct. 10-11 for an invited research talk titled “Tick immunity vs. pathogen persistence: the molecular tug of war that shapes vector competence” and was also the recipient of WSU’s 2023 Pacesetter Award!

September 2023

  • The Fall semester has started and we have new faces in the lab! Alyssa Maine, a first-year IID PhD student, and Cierra Grove, an undergraduate Genetics and Cell Biology MARC Scholar, are joining us for rotations - welcome Alyssa and Cierra!

  • Dana traveled to Iowa City, IA to visit the University of Iowa College of Medicine and old friend from grad school, Mary Weber, PhD. She presented a seminar titled “From stress to defense: unraveling the UPR’s role in tick immunity and vector competency” and had an excellent time visiting with Mary and the University of Iowa folks!

  • The lab’s most recent story is now available on mSphere and was chosen as the Editor’s pick!

    • In this story, we address what sorts of elements allow tick-borne pathogens to survive in ticks. We know that tick immune responses produce molecules that restrict transmissible pathogens like Borrelia and Anaplasma. So how are these microbes persisting in ticks?

    • We found that the PERK-eIF2α-ATF4 pathway is induced in infected Ixodes ticks, which leads to an Nrf2-driven antioxidant response. Activity of this pathway supports microbial persistence by detoxifying reactive oxygen and nitrogen species.

    • Overall, these results highlight the mechanistic push and pull between arthropod immunity and pathogen persistence in ticks!

May 2022

We have many things to celebrate this month in the Shaw lab!

  1. Lindsay Sidak-Loftis was selected as a 2022-2023 Poncin Fellow! This award is intended to aid worthy and ambitious young people who are engaged in biomedical research at any recognized institution of learning within the State of Washington. This is a well-deserved recognition of Lindsay’s research accomplishments and potential. Congratulations, Lindsay!

  2. Ashley Warren is joining us as the newest Shaw lab member! Ashley comes to us with a DVM from Cornell University and is now an IID graduate student in the combined Residency/PhD program. Welcome, Ashley!

  3. Ashley is also the winner of the Design a Better Pathogen competition this year! Ashley’s pathogen, Balamuthia millennii, is the causative agent of Millennial Encephalic Amoebiasis and is transmitted through contaminated avocados. A secreted effector molecule, KaREN, causes behavioral changes resulting in symptoms such as an affinity for brunch and avocado toast.

    The Design a Better Pathogen competition is the final project of the IID program course, Mechanisms of Disease. This is an exercise where students will dream up a satirical pathogen and give a 10 min. presentation to the department that introduces the microbe and describes mechanisms that cause the associated disease. At the end presenters then field questions from the audience. Congrats to Ashley on a well-deserved win!

April 2022

This spring Ashley Warren, one of VMP’s new combined Residency/PhD students, will be rotating with us - welcome, Ashley!

Our new story is now up on BioRxiv! “The unfolded protein response triggers the ancestral immune deficiency pathway

In it, we expand on a previous observation that the tick genome does not have genes encoding crucial IMD pathway initiators such as IMD or transmembrane PGRPs… so how does the pathway function then?

Collaboration and crosstalk! Turns out a cellular stress response network, the UPR, initiates the IMD pathway in ticks. Stress response pathways are ancient networks that respond to environmental stressors - including infection! Pathogens can cause stress to host cells by parasitizing nutrients and in some cases also causing physical damage.

We found that IRE1α pairs with TRAF2 to induce antimicrobial defenses, including IMD pathway antimicrobial peptides and reactive oxygen species. Through in vitro, ex vivo and in vivo approaches, we show that disabling this pathway leads to increased Borrelia burgdorferi and Anaplasma phagocytophilum burdens in Ixodes scapularis ticks. AND that this interaction occurs in multiple tick species as well as Drosophila! This suggests that UPR-IMD pathway crosstalk was present in a common ancestor to insects and arachnids, and likely an ancient mode of host defense against infection!

August 2021

The Fall semester has started and 1st year Immunology and Infectious Disease PhD student, Kaylee Andrews, will be joining us for her first rotation - welcome!

This month an Opinion article authored by Dana and two collaborators, Jason Park and Adela Oliva Chavez, was accepted into Frontiers in Cellular Infection and Microbiology. In it, we talk about the arthropod-side of tick-borne disease as an area that needs more research focus including 1) Barriers within the tick that pathogens must overcome, 2) Tick-pathogen interactions and microbial manipulation of the tick, and 3) How tick saliva content contributes to pathogen transmission dynamics. Check it out here Ticks: More than just a pathogen delivery service.

For her hard work, Lindsay was awarded a travel award and will advance to the university-wide 3 Minute Thesis competition where she will represent the CVM. Good luck, Lindsay!

December 2020

The Shaw Lab is finishing 2020 on a high note! First, Lindsay Sidak-Loftis successfully defended her proposal, passed prelims and advanced to PhD candidacy - congrats, Lindsay!

Second, the lab’s first manuscript was accepted to Frontiers in Immunology! Our Perspective, titled “Arthropods Under Pressure: Stress Responses and Immunity at the Pathogen-Vector Interface”, will be published as part of the Research Topic “Ticks and Host Immunity – New Strategies for Controlling Ticks and Tick-Borne Pathogens”. In it we describe two well-characterized and evolutionarily conserved mechanisms, the Unfolded Protein Response (UPR) and the Integrated Stress Response (ISR), and examine evidence that these stress responses impact immune signaling. We then describe evidence that vector-borne microbes interface with stress responses in mammals. Owing to the well-conserved nature of the UPR and ISR, we speculate that similar mechanisms may be occurring in arthropod vectors and ultimately impacting vector competence. We conclude by positing that novel insights into vector competence will emerge when considering that stress-signaling pathways may be influencing the arthropod immune network.
