We are delighted to see that the latest study on the mechanisms of chemo-resistance in T-cell Acute Lymphoblastic #Leukemia (T-ALL) by Jingliao Zhang and colleagues is now published in the prestigious journal, Blood!

T-ALL is an aggressive cancer not least because of the propagation of resistant cancer clones that drive disease recurrence. Jingliao Zhang et al. (Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College) wanted to dissect the nature of these clones to work out how their presences might contribute to resistance to #chemotherapy .

Combining single cell RNA sequencing with T-cell receptor sequencing of paired diagnosis-relapse T-ALL samples, the researchers identified two leukemic evolutionary patterns: “clonal shift” and “clonal drift”. They additionally saw high expression of the RNA-binding protein MSI2 in the clones persisting at the point of disease relapse. Digging deeper, the researchers conducted functional studies showing that MSI2 contributed to T-ALL proliferation and promoted #chemoresistance through the posttranscriptional regulation of the #oncogene, MYC.

These findings have important implications, as they identify MSI2 as an informative biomarker and novel therapeutic target in T-ALL.

New insights into physiological and pathological brain wiring

We’re excited to share news of the publication of a fantastic article by an IEL client last month, edited by IEL’s Ilya Demchenko.

Published in PNAS as an open access article, Sinclair-Wilson and colleagues describe their ground-breaking work on the plasticity of brain circuits in neonates, which is important for the correction of embryonic thalamocortical axon mis-targeting. Using a genetic mouse model, the researchers identified a serotonin-dependent window in the immediate post-natal period in which pre-natal axon miswiring can be corrected and appropriate definition of cortical areas rescued: this period was disrupted by pre-term birth and dysregulation of serotonin levels. This work may have profound implications for our understanding of human neurodevelopmental disorders that occur in extremely pre-term infants.

Well done to everyone involved in this groundbreaking study – it was a pleasure working with you and we look forward to learning how this work progresses in the future!

Veterinary mycoplasmas: updates and knowledge gaps

We are so excited to present this latest research report, commissioned by the US Department of Agriculture (USDA) Agricultural Research Service (ARS) and STAR-IDAZ International Research Consortium on Animal Health and authored by our own Daniel AckermanLaura Roden and Lucy Robinson.

Our team was given the challenge of reviewing all the literature on veterinary mycoplasmas of interest (3500 papers!), selecting those studies that presented important findings, and collating the data from the field into a coherent and engaging summary document that can be used by researchers and policy-makers to help identify important knowledge gaps.

We are super-proud of this work, and have high hopes that it will be a significant help in guiding resources to those areas most in need of further research.

Thanks again to the commissioning team at STAR-IDAZ International Research Consortium on Animal Health for your support during the writing, and to all the researchers who reviewed and made suggestions to improve the report along the way: Georgina GrellMadeline NewmanAlex MorrowNicholas JuleffRoxann Brooks Motroni DVM, PhD, Rachel Wood, Mark Ackerman, Jeff Caswell, Rohana Dassanayake, Jeff Evans, Patrice Gaurivaud, Bryan Kaplan, Dominiek MaesMusa Mulongo, Robin Nicholas, Jose Perez-CasalSacchini FlavioMassimo Scacchia and Dan Tucker.

This is not the first time the IEL team have been involved in compiling literature reviews – in fact, it is becoming quite a specialty! We really enjoy digging deep into a subject area and teasing out the ongoing issues and areas for future research. Get in touch if you would like support on a literature review for your topic of interest!

Findings published in Frontiers in Immunology earlier this year show that hepcidin is a potent marker of septic shock and other acute inflammation-associated pathologies!

Marcela Hortova-Kohoutkova and colleagues aimed to understand whether the dynamics of iron regulation could be used as a biomarker for inflammatory disease severity. In their cohort, comprising patients with #septicshock and #covid19, they saw that elevated hepcidin levels reflect overall immune-cell activation driven by intrinsic stimuli, while ferritin levels were boosted by pathogen-induced inflammation.

Hortová-Kohoutková et al. ultimately propose that the hepcidin-to-ferritin ratio could identify those at risk of mortality in septic shock. These findings have amazing clinical potential and we are really excited to see how they translate going forward!

New findings on how pulmonary metastases form in gastric cancer (GC) have been published in the Journal of Cellular Biochemistry!

Ming Wang and colleagues at Henan University, investigated how extracellular vesicles known as exosomes might help GC cells metastasize to the lungs, using mouse forestomach carcinoma cells as their model system. They found a novel mechanism by which GC-derived exosomes mediate PD-L1 expression in lung macrophages (which helps cancer cells evade immune detection), which in turn facilitates lung pre-metastatic niche formation. Wang et al. hypothesize that these findings might one day translate into a future potential therapeutic target for GC with pulmonary metastases.

Publication Success!

Earlier this month, Springer Nature Technology and Publishing Solutions published the Handbook of Cancer and Immunology, and it is a “must read” for anyone looking for a comprehensive yet accessible and up-to-date overview of the latest advances in cancer immunology and #immunotherapy.

We were delighted to work with Joe YEONG 杨宝诚 and colleagues Institute of Molecular and Cell Biology and Nanyang Technological University Singapore on the chapter: The Hurdle of Precision Medicine in Cancer Immunotherapy: Personalization Now or Then?

This chapter alone is a fascinating and important resource that raises important questions and suggestions for future research to advance this field.

Take a look:

Congratulations to everyone involved in creating this important resource!
