'Here we examine the contribution of Mitogen Activated Protein Kinase (MAPK) signaling on IFNλ-mediated antiviral activity. We find that extracellular-signal-regulated kinase 5 (ERK5), a poorly characterized member of the conventional MAPK family, potentiates the antiviral efficacy of IFNλ.'

"Repurposing generic medicine has the potential to bring new treatments for infectious diseases to patients efficiently and equitably. In this study, we found that intranasal delivery of neomycin, a generic aminoglycoside antibiotic, induces the expression of interferon-stimulated genes (ISGs) in the nasal mucosa that is independent of the commensal microbiota."

from ⬆️ "These nettles are renowned for inflicting extremely painful stings that are characterized by acute electric shocklike, piercing, pricking and burning sensations lasting for many hours, followed by intermittent painful flares and allodynia that persists for days or even weeks."

Similarities to other types of neuropathic pain, including small fiber neuropathy and Long Covid associated neuropathy.

"These results provide important insights into the function of NaV channels in sensory neurons, identify TMEM233 as a previously unknown NaV1.7interacting protein, and describe the dispanins as bifunctional proteins that cause allosteric changes in channel gating upon binding of pain causing venom peptides."

Not finding much on TMEM233. Some dispanins are interferon activated.

review article from 2012:
- The Dispanins: A Novel Gene Family of Ancient Origin That Contains 14 Human Members

"The IFITM1–3 proteins were identified 25 years ago as being upregulated by interferons (IFN) [6]. Recently they received considerable attentions as IFITM1–3 were found to prevent infection of a growing list of viruses such as HIV-1, SARS influenza A H1N1, West Nile and Dengue fever viruses [7], [8], [9], [10]. Hence, proteins of the IFITM family mediate part of the antiviral response orchestrated by IFNs. However, the IFITM family is also involved in other processes such as oncogenesis, bone mineralization (IFITM5) and germ cell development (IFITM1 and 3) and IFITM5 has not been identified as interferon-inducible [11], [12], [13], [14]. Although the biological roles of the IFITM genes are emerging, no thorough evolutionary analysis has been performed on this group.

In this study, we sought to infer the evolutionary history of the human IFITM genes and identify potential homologues. We mined 36 eukaryotic species, covering all major eukaryotic groups, and found that the IFITMs form a subfamily in a larger novel family that has ten human members in addition to the four IFITM genes. We propose Dispanins as a novel name for this family, which refers to their common 2TM structure. "

Always been curious how different interferons that signal through same receptor can have different functional effect. Here's a paper that shows how:
#interferon #immunology #receptor #receptors #Signalling https://www.science.org/doi/10.1126/scisignal.adf5494

Researchers found that #interferon-gamma signaling caused hyperactivation of ERK in human #melanoma cell lines. The #ERK protein, when hyperactive, causes stress in the #cell, and this stress ultimately leads to cell death through specific proteins called #DR5 and #NOXA

Now I cant stop singing "more than a spike gene" to the tune of the BeeGees (protein didnt fit the meter).

'We assessed the role of ORF6 during infection using recombinant viruses carrying a deletion or loss-of-function (LoF) mutation in ORF6. ORF6 plays key roles in interferon antagonism and viral pathogenesis by interfering with nuclear import and specifically the translocation of IRF and STAT transcription factors.'

'Here, we used CRISPR-based loss-of-function screens to identify a markedly limited set of ISGs that confer interferon-mediated suppression of a model alphavirus, Venezuelan equine encephalitis virus (VEEV). We show via combinatorial gene targeting that three antiviral effectors—ZAP, IFIT3, and IFIT1—together constitute the majority of interferon-mediated restriction of VEEV, while accounting for < 0.5% of the interferon-induced transcriptome.'

"Our investigation reveals that the fetal HSCs respond to T. gondii infection with virulence-dependent changes in proliferation, self-renewal potential, and lineage output. Furthermore, maternal IFNγ crosses the fetal–maternal interface, where it is perceived by fetal HSCs."
