Infectious Diseases doctor (at UCLH) and academic (at UCL). Research focuses on host-pathogen interactions in TB, leprosy and UTIs. What are the immune, epithelial and stromal cell responses involved, and could they be targets for host-directed therapies?

Excited to share this “Insight” @jem.org about an amazing new finding by Zhou, Zhang, Ye, Staeheli &co showing that type III interferons #IFNL also signal in #fibroblasts driving renal #fibrosis! #InterferonPower! #EveryCellIsAnImmuneCell! #FriendsOrFoes!

IFNλ works at mucosal surfaces by signaling in epithelial cells and selected immune cells. Zhou, Zhang et al. (rupress.org/jem/article/...) demonstrate that IFNλ also signals in kidney fibroblasts sustaining renal #fibrosis. @lozanzi.bsky.social highlights the findings: rupress.org/jem/article/...

Great post @apsmunro.bsky.social! Doing more is such a natural reaction. But even 'benign' interventions may likely be harmful when tested properly. I'm yet to know of a trial for sepsis where adding antibiotics has been beneficial (outside of TB where we do it to prevent emergence of resistance).

My new post looks at two antimicrobials which have been routinely used and even recommended in guidelines despite a lack of RCT evidence In the last few weeks they’ve both been shown to have no benefit, and worse, high probability of harm - killing patients A lesson we keep failing to learn

The current #Ebola outbreak in DRC has the potential to be even larger than those in 2018 and 2014. Why have we seen larger outbreaks in recent years? There are multiple reasons including conflict, population movement and urbanization. But the trend shows we must learn how to respond better

Excited to share my first-author research letter! Our findings highlight an important question: how therapies perform outside of clinical trials, particularly among patients often underrepresented in research. Thank you @jamanetworkopen.com! @unmccom.bsky.social @unmc-id.bsky.social

In clinical practice, patients with #Bacteremia receiving dalbavancin were younger and more likely to have substance use or housing instability than those in the DOTS trial, but completed therapy with similar low failure rates. ja.ma/4odctAk

Table 2. Cohort Outcomes Comparisons. DOTS trial (n=100) shows 80% overall clinical success at day 70 & 73% composite efficacy, vs. clinical dalbavancin recipients (n=31) with 65% and 61% respectively.

Very pleased the @who.int Programme Managers guide for control of scabies in low income settings now out. In many areas population prevalence of scabies is 10-30% making it a major public health problem. This guide is designed to assist Ministries of Health & NTD teams in scaling up interventions.

Intravital imaging showed these macs nibbling and engulfing live melanoma cells. This was independent of PS receptor MERTK. How are they able to recognise and phagocytose melanoma cells without opsonisation by antibodies? Can we exploit this for cancer immunotherapy? Lots to do! Please share! 2/2

It's been a while time to give #immunology @bsky.app another go...Thrilled to share work led by Dr Yuki Keith & colleagues @garvaninstitute.bsky.social, UNSW & Melanoma Institute Australia now out @jem.org. CD169+ macs in skin surround & constrain melanoma growth independent of T and B cells! 1/2

this is cool - haematopoietic stem cell subsets that remember inflammatory cues. Link to human disease mortality a bit loose, personally, and not much functional readout of progenitor cells. Still, paper concept interesting, and yet another single cell popn to hunt in own datasets.... #ImmunoSky

#WeekendRead! #EveryCellIsAnImmuneCell! #RememberMe! Xie, Zeng, Nagree, Jakobsen &co show @nature.com that upon TNF or LPS-driven inflammation, a subset of hematopoietic stem cells retains inflammatory epigenetic memory that can be transferred to immune cell progeny boosting all-cause mortality risk
