Synthesis pass · prose summary of the discoveries below

IL4R encodes the IL-4Rα chain, the shared ligand-binding subunit of the type I (IL-4Rα/γc) and type II (IL-4Rα/IL-13Rα1) receptor complexes that transduce IL-4 and IL-13 signals across hematopoietic and non-hematopoietic cell types (PMID:9013879, PMID:9301536, PMID:15331327). Discrete cytoplasmic domains couple to distinct downstream pathways: Y497 and Y713 mediate anti-apoptotic signaling, the first conserved tyrosine (Y1) activates PI3K/mTOR to drive G2/M cell-cycle progression, and the ID-1 region signals through STAT5 for S-phase entry independent of cytoplasmic tyrosines, while the canonical output is JAK1-dependent STAT6 phosphorylation (PMID:9670964, PMID:16210622). Disease-associated coding variants alter pathway output—the R576 gain-of-function variant recruits GRB2 to activate ERK→IL-6→STAT3 signaling, reprogramming Tregs toward a TH17 fate in asthma, while the somatic I242N transmembrane mutation drives constitutive JAK-STAT activation in primary mediastinal large B-cell lymphoma (PMID:27479084, PMID:29467182). Beyond canonical immunity, IL-4Rα on smooth muscle cells controls intestinal contractility during helminth infection, on inhibitory neurons mediates T-cell-derived IL-4 effects on synaptic plasticity and episodic memory, and its surface expression is regulated post-transcriptionally by glucocorticoids, intronic SNP-dependent alternative splicing, and IGF2BP3-mediated mRNA destabilization (PMID:20360135, PMID:34793707, PMID:9847438, PMID:16917945).

1997 IL-4Rα and IL-13Rα1 together reconstitute a functional high-affinity IL-4/IL-13 receptor complex: CHO cells co-expressing both chains bound IL-13 with Kd ~30 pM and allowed cross-competition of IL-13 and IL-4, whereas each chain alone could not activate STAT6; IL-4Rα alone did not bind IL-13. Receptor reconstitution in CHO cells (co-expression), radioligand binding, electrophoretic mobility shift assay (EMSA) for STAT6 activation FEBS letters High 9013879
1997 IL-13 signals through IL-4Rα in human endothelial cells: a neutralizing anti-IL-4Rα monoclonal antibody blocked IL-13-induced MCP-1 expression; IL-13 and IL-4 both caused rapid tyrosine phosphorylation of immunoprecipitated IL-4Rα and activated STAT6. Neutralizing antibody blockade, immunoprecipitation with phosphotyrosine detection, EMSA for STAT6 Immunology High 9301536
1998 Tyrosine residues Y497 and Y713 within the cytoplasmic tail of IL-4Rα are required for IL-4-mediated protection from apoptosis; the domain containing the STAT6-docking tyrosines suppresses this protection. Transplantation of Y497 or Y713 domains to a truncated IL-2Rβ partially conferred protection, and Y→F mutation abolished it. Cytoplasmic domain transplant chimeras, site-directed mutagenesis (Y→F), apoptosis assays in 32D cells Journal of immunology High 9670964
1998 Glucocorticoids (dexamethasone) down-regulate IL-4Rα expression by two distinct posttranscriptional mechanisms: (1) PMA-induced IL-4Rα expression is suppressed by decreasing mRNA half-life; (2) IL-4-induced IL-4Rα expression is suppressed at the translational or posttranslational level without changing mRNA stability or transcription rate. The effect is glucocorticoid-receptor-dependent (reversed by RU486). Northern blot, nuclear run-on transcription assay, flow cytometry, mRNA stability assay, GR antagonist (RU486) The Journal of allergy and clinical immunology High 9847438
1999 The allergy-associated IL-4Rα mutation Q576R (Q551R in some numbering) does not significantly alter IL-4-induced tyrosine phosphorylation, STAT6 DNA-binding, proliferation, apoptosis protection, or CD23 induction compared to wild-type receptor in murine cells expressing human IL-4Rα cDNA, indicating this variant does not directly enhance IL-4 signal transduction. Transfection of WT and mutant (Q576R, Y575F) human IL-4Rα cDNA in murine cells, phosphorylation assays, EMSA, proliferation and apoptosis assays, CD23 induction Journal of immunology High 10201973
2001 IL-13-induced airway hyperreactivity and eosinophilia can occur independently of IL-4Rα but requires STAT6, revealing a novel IL-13 signaling pathway through a different receptor component that involves STAT6 without IL-4Rα.

2004 The IL-4Rα variant encoding isoleucine at position 50 (I50) acts as a gain-of-function allele relative to V50 for STAT6-dependent transcriptional activity, but this enhanced STAT6 signaling does not increase Th2 differentiation efficiency or IL-4-mediated repression of Th1 development.

2004 IL-13E13K (an IL-13 mutant antagonist) inhibits IL-4 binding and STAT6 phosphorylation in cells expressing the type II IL-4R (IL-4Rα/IL-13Rα1 heterodimer) but not type I IL-4R (IL-4Rα/γc), because Glu13 of IL-13 contacts IL-4Rα and its mutation to lysine prevents IL-13Rα1/IL-4Rα heterodimerization. Receptor-specific cell lines, competitive binding assay, STAT6 phosphorylation assay, protein synthesis inhibition assay Cellular immunology High 15331327
2005 In primary T cells, IL-4Rα lacking all cytoplasmic tyrosines can still signal for STAT5 phosphorylation and S-phase entry via an intact ID-1 region; Y1 (first conserved tyrosine) activates the PI3K/mTOR pathway to promote G2/M progression, and rapamycin blocks cell-cycle completion but not S-phase entry downstream of IL-4Rα.

2006 IL-4Rα/STAT6 signaling in bone marrow-derived (hematopoietic) cells is both necessary and sufficient for protection against acute schistosomiasis by enabling alternatively activated macrophage generation and suppressing IL-12/TNF/IFN-γ-driven inflammation; IL-4Rα signaling in non-hematopoietic cells governs granuloma size and fibrosis but not survival.

2006 IL-4Rα signaling is required for IL-10 production by an IL-10+ Th2 subpopulation, and IL-10 is the key IL-4Rα-dependent factor that suppresses Th1 responses to maintain Th2 dominance during nematode infection.

This was demonstrated with an IL4R minigene construct and confirmed in human mRNA samples; splicing factors SRp20 and YT521-B modulate this. Minigene splicing assay, mRNA quantification in human samples, splicing factor overexpression Human mutation High 16917945
2010 IL-4Rα responsiveness in smooth muscle cells (non-hematopoietic) is required for IL-4/IL-13-mediated intestinal hypercontractility, which in turn promotes S. mansoni egg expulsion and host survival during acute schistosomiasis; smooth muscle cell-specific IL-4Rα deletion increased susceptibility independently of Th2 cytokine levels.

2011 IL-4Rα signaling in rhabdomyosarcoma activates STAT6, Akt, and MAPK pathways; IL-4 and IL-13 stimulation promotes tumor cell proliferation and downregulates MyoD and Myogenin (myogenic differentiation factors); neutralizing anti-IL-4Rα antibody in a mouse ARMS model significantly reduced lymph node and pulmonary metastases.

2016 An asthma-associated IL-4Rα variant (R576) promotes conversion of induced Treg cells to TH17-like cells by recruiting the GRB2 adaptor protein, which activates ERK → IL-6 → STAT3 signaling to drive IL-17 expression. Treg-specific deletion of IL6ra or Rorc (but not IL-4 or IL-13) prevented exacerbated airway inflammation in Il4ra(R576) knock-in mice. R576 knock-in mice, Treg-specific conditional knockouts (IL6ra, Rorc, IL-4, IL-13), GRB2 co-immunoprecipitation, ERK/STAT3 pathway analysis, anti-IL-6 antibody treatment Nature medicine High 27479084
2018 Somatic IL4R mutations (most commonly I242N in the transmembrane domain) in primary mediastinal large B-cell lymphoma (PMBCL) are gain-of-function, causing constitutive JAK-STAT pathway activation, upregulation of downstream cytokine expression, and growth advantage in vivo in a mouse xenotransplantation model.
