C. albicans promotes EGFR degradation through Ece1p and Als3p, predominantly mediated by the lysosomal pathway, and induces the recruitment of adaptor proteins Grb2, AP2M1, and HRS. ( A–C ) TR146 cells were infected with different C. albicans strains (wild-type [WT] SC5314, ece1 Δ/Δ and als3 Δ/Δ) or stimulated with PBS as a vehicle control for 2 h (MOI 10), 8 h (MOI 1), and 12 h (MOI 1). Cell lysates were electrophoresed on gradient gels to detect total EGFR and α-actin via Western blot. Data are representative of three independent experiments. ( D and E ) TR146 cells were pre-treated for 1 h with 0.25 µM of lysosomal inhibitor Bafilomycin A1 (BafA1) and 10 µM of proteasomal inhibitor MG-132 or DMSO as a vehicle control, and then treated with 100 ng/mL EGF as a positive control for 1 h or infected with SC5314 (MOI 5) for 10 h.

doi: 10.1186/s40001-025-03583-3

Figure Lengend Snippet: AP2M1 is associated with Wnt signaling pathway. A Relative mRNA expression of AXIN2 (Wnt), HES1 (Notch), and GLI1 (Hedgehog) following AP2M1 knockdown in HepG2 cells. Data were quantified and expressed as the mean ± SEM of 3 independent experiments. **p < 0.01, ***p < 0.001 vs. value in the negative control. B Relative mRNA expression of AXIN2 (Wnt), HES1 (Notch), and GLI1 (Hedgehog) following AP2M1 knockdown in Hep3B cells. Data were quantified and expressed as the mean ± SEM of 3 independent experiments. **p < 0.01, ***p < 0.001 vs. value in the negative control. C Relative mRNA expression of axin2 (Wnt), her6 (Notch), and gli1 (Hedgehog) in 48hpf zebrafish embryos was detected by RT-PCR. Data were quantified and expressed as the mean ± SEM of 3 independent experiments. **p < 0.01 and ***p < 0.001 vs. value in the negative control

Article Title: A cytoplasmic motif in HLA-E that drives clathrin-mediated endocytosis and VCP-associated postendocytic trafficking

doi: 10.1073/pnas.2514956122

Figure Lengend Snippet: The unconventional endosomal transport of HLA-E depends on CME and VCP-dependent surface return. ( A ) Immunoblot for AP2M1 in HEK293T cells with AP2M1 knocked out. ( B ) HLA internalization rates after 1 h in WT HEK293T cells or HEK293T cells with AP2M1 knockout ( AP2 -KO), which were transiently transfected with the indicated HLA constructs, or cotransfected with HLA constructs and WT AP2M1 (AP2 WT) or its dominant-negative mutant (AP2 D176A). Internalization assays were carried out as described in Fig. 1 D . ( C ) Immunoblot for CLTC in HEK293T cells with CLTC knocked out with two different gRNAs (KO.1, KO.2). ( D ) HLA internalization rates after 1 h in WT HEK293T cells or HEK293T cells with CLTC knocked out were transiently transfected with the indicated HLA constructs. Internalization assays were carried out as described in Fig. 1 D . ( E ) Diagram illustrating the ELISA-based peptide binding assay (created with BioRender.com). ( F ) The binding of the cytoplasmic tails of CD1, HLA-E, and their respective mutated versions lacking the binding motif to the AP-2 complex was assessed by ELISA, as illustrated in E . Data were collected for five replicates (three technical repeats/run) and are shown as mean ± SEM. ( G ) Sequences of the cytoplasmic tail of different constructs. Sequence identity is indicated by dots and mutated positions are highlighted in red. ( H ) Immunoblot for VCP in HEK293T cells with siRNA-mediated VCP knockdown or after overnight incubation with NMS-873 (5 nM) and CB-5083 (2 nM). ( I ) Recycling of HLA-E after 1 h in HEK293T cells with siRNA-mediated VCP depletion or following overnight incubation with NMS-873 (5 nM) or CB-5083 (2 nM) with or without VL9 peptide (50 µM) during internalization. Recycling assays were carried out as in Fig. 3 A . ( J ) Recycling of HLA-E after 1 h in HEK293T cells incubated with chloroquine (CQ, 20 µM) overnight with or without VL9 peptide (50 µM) during internalization. Recycling assays were carried out as Fig. 3 A . Data were collected from six ( B and D ) or five ( H and I ) replicates and are presented as mean ± SD (error bars). Statistical analyses were performed using one-way ANOVA with Tukey’s post hoc test ( B , D , and H ) or paired two-tailed t test with Welch’s correction (F, I). Asterisks denote statistical significance: ns, not significant; * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001.
