We’re hiring! Looking for a laboratory post-doc fellow to help us disentangle protective and pathogenic T cells in TB, so we can stratify disease-risk after infection, and develop more effective vaccines.

Come on down, anyone eligible for a post-doc do consider applying for this exciting project with @jennyrohn.bsky.social, @scottishwormboy.bsky.social & me!

Got a touch of #UTISky #IDSky #ImmunoSky & 🧪 about it! 😉

We also hope Metaclonotypist will prove to be a valuable application for fast and flexible parameter optimisation for identification of T cell metaclones across wide-ranging disease domains.

Given the critical role of T cell immunity in TB, we are excited about the potential for using generalisable T cell metaclones for improved disease-risk stratification in Mtb-infected people, and for identification of T cell epitopes for development of more effective vaccines.
mnoursad.bsky.social
Although the predominant repertoire of T cell reactivity to Mtb epitopes is private to individuals, we found striking evidence for population-wide immunodominance at the level of individual pMHC specificity revealed by highly generalisable/public T cell metaclones.
mnoursad.bsky.social
To overcome inter-individual TCR sequence diversity for shared peptide-MHC specific responses to Mtb , we developed a new computational pipeline, Metaclonotypist, to identify HLA-associated clusters of similar TCR sequences (metaclones) across a large ethnically diverse study population.
mnoursad.bsky.social
We used the tuberculin skin test as a standardised in vivo challenge comprising the whole Mtb proteome to generate localised enrichment of Mtb reactive T cells derived from the whole in vivo repertoire, which we characterised by TCR sequencing.

Fab analysis @hannahrickman.bsky.social - will we be well cited. are there sex-stratified data for house-hold contacts for which we may expect similar exposures?

Best #Nikolaus 🎅! Our paper on how the 🫁 microenvironment can shape #innate immunity against #viruses is out @sciimmunology.bsky.social This was a herculean effort brilliantly led by @pauljbaker.bsky.social who singlehandedly established the model in the lab during the pandemic. 🧪 #Immunosky 1/9
Graphical summary of our paper.  In mice, prior lower airway exposure to diverse inflammatory stimuli, including chronic bacterial infections such as M. tuberculosis, acute bacterial infections such as pulmonary S. aureus, viral infections such as Influenza A, type-II allergic responses such as the OVA-Alum model, activation of pulmonary TLR9 by CpG or pulmonary TLR1/2 by Pam3CSK4
 leads to reduced viral burden upon subsequent infection with SARS-CoV-2 (SCV2). (2) This SCV2 restriction occurs prior to induction of SCV2-specific adaptive immune responses 
and is mediated through innate immune responses, including the induction of IFN-I, TNFα and IL-1 and sustained changes to the TRM (Tissue resident macrophage) cellular 
compartment and the pulmonary epithelium. (3) Innate cytokine and TLR signaling to both recruited immune cells and the pulmonary epithelium creates a microenvironment in the 
lung that limits early replication of SCV2. IFN-I signaling to pulmonary ECs (epithelial cells) increases expression of interferon-stimulated genes, that likely cell-intrinsically limit viral
 replication. TNF- or IL-1 suppress SCV2 independently of IFN-I signaling. TNF acts exclusively through radio-resistant cell types such as the lung epithelium, whereas IL-1 affords 
control both direct and indirectly, through either stromal and hematopoietic cell types, to restrict overall early SCV2 burden.

Exciting- live to hear more!

important point- have not done this yet- wonder whether protein as dynamic as transcripts

and these data from unselected acute respiratory viruses in community acquired infection - with longitudinal sampling after the symptom onset
mnoursad.bsky.social
Not sure if I have misunderstood- our findings that distinct biomarkers discriminate early & late phases of infection were generalisable to all acute respiratory viruses we have been able to test - panel on right = extended time course from Flu challenge
