Genetics of Immune Signalling
Immune signalling pathways coordinate communication between immune cells and between immune and non-immune cells. Genetic variants in cytokine receptors, signal transducers, and downstream effectors shape immune response dynamics.

What is Immune Signalling?
Immune cells communicate through cytokines, chemokines, and contact-dependent signalling. These signals are transduced intracellularly through pathways including JAK-STAT, NF-kB, MAPK, and PI3K-AKT, ultimately altering gene expression and cell behaviour. The precision of these signalling networks determines whether immune responses are appropriately calibrated and resolved, or dysregulated and chronic. Genetic variation in signalling pathway components creates individual differences in immune response dynamics that may influence susceptibility to chronic inflammatory conditions.
Biological pathways commonly discussed in relation to Immune Signalling
Research into Immune Signalling Pathways and Cell Communication has highlighted several biological pathways that may be relevant. Genetic variants within these pathways may influence individual susceptibility, symptom severity, or the trajectory of the condition.
Cytokine Receptor Signalling
IL-6 receptor (IL6ST, IL6R), TNF receptor (TNFRSF1A), and IL-1 receptor signalling transduce pro-inflammatory cytokine signals. Variants affecting receptor expression or downstream signalling alter cytokine sensitivity.
Chemokine Signalling
Chemokines (CCL2, CXCL10, CX3CL1) and their receptors (CCR5, CXCR3, CX3CR1) guide immune cell trafficking. Variants like CCR5 delta32 can dramatically alter chemokine biology and infection susceptibility.
Pi3k Akt
PI3K-AKT signalling regulates immune cell survival, activation, and metabolism. Variants in PI3K subunits and PTEN (its negative regulator) affect immune cell homeostasis.
Negative Feedback
SOCS1, SOCS3, A20 (TNFAIP3), and other negative regulators terminate cytokine signalling. Variants reducing negative feedback may lead to hyperresponsive or sustained immune activation.

How personal DNA data may provide educational insights
Consumer DNA files from 23andMe, AncestryDNA, and MyHeritage contain raw SNP data. When you upload your file to ChronicDNA, the analysis engine checks your genotype against a curated panel of 80+ genes selected for their relevance to Long COVID, ME/CFS, and connected biological pathways - some of which may relate to areas such as Immune Signalling.
This is not a diagnostic service. Genetic variants do not determine whether you have Immune Signalling, nor do they predict your clinical outcomes. The report is educational - it explains which variants you carry, what the research says about them, and how they fit into the biological pathways most relevant to chronic illness. All results should be discussed with a qualified healthcare provider.

Frequently asked questions
What is immune signalling?
Immune signalling refers to the molecular communication pathways through which immune cells receive, process, and respond to cytokine and chemokine signals. Genetic variants affecting these pathways can alter immune response intensity, duration, and resolution.
What is CCR5 delta32 and why is it significant?
CCR5 delta32 is a 32-base-pair deletion in the CCR5 gene that prevents functional CCR5 expression on cell surfaces. Homozygous carriers are highly resistant to HIV-1 infection. Heterozygous carriers may have altered immune responses. This variant has also been studied in relation to COVID-19 outcomes.
What are SOCS proteins and why do they matter?
SOCS (Suppressors of Cytokine Signalling) proteins provide negative feedback to JAK-STAT signalling, limiting the duration of cytokine responses. Variants reducing SOCS function may result in prolonged cytokine signalling and potentially contribute to chronic inflammatory states.
Which immune signalling genes are most studied in chronic illness?
Key genes include IL6R, IL6ST, TNFRSF1A, CCR5, CXCR3, SOCS1, SOCS3, CX3CR1, TNFAIP3, and PTPN2. These cover cytokine receptor biology, immune cell trafficking, and signal termination.
