(A) Schematic of the e xperimental setup to study AXL-GAS6/PROS1 interaction using aFRET in mouse lung tissue sections. Lungs were isolated on day 4 post DT. aFRET is a coincidence assay, labels both receptor (AXL) and ligands (GAS6 or PROS1) (see Methods for details). FRET occurs in the range of 1-10 nm. Scheme was created in BioRender. Geillinger-kästle, K. (2025) https://BioRender.com/h45x771 (B) Representative image of AXL-GAS6 interaction. (C) Representative image of AXL-PROS1 interaction. (B-C) Upper figures showed the mean of the donor lifetime (Ƭ) in the absence of acceptor. Lower figures showed the interaction state between AXL-GAS6/ PROS1 for each coincidental region (marked by yellow and black circles). Different coincidental regions possessed different interaction state. (D) Box and whiskers plots showed the heterogeneity of AXL-GAS6/PROS1 interaction states represented as FRET efficiency (Ef%). Ef% below 4% represents the Förster Radius (R 0 at 5.83nm) and not proteins, interactive state as marked by red dashed line. Data are shown as box and whiskers plot of n=5-6. Each dot represents median of Ef% for each mouse. P ≤ 0.05 (*). (E) Correlation plot between Ef% AXL-GAS6 and AXL expression. (F) Correlation plot between Ef% AXL-PROS1 and AXL expression. (G-H) Surface plasmon resonance response curve showing the binding of rhGAS6 and rhPROS1 in different concentration to rhAXL. (I-J) Concentration dependent binding of rhGAS6 and rhPROS1 to rhAXL. Different colored lines in (G-H) correspond to different colored dots in (I-J), which indicate different concentrations of rhGAS6 and rhPROS1. (K-L) GAS6 and PROS1 concentration in human BALF of non- diseased control, ILD/IPF-, and COPD patients. Data are shown as mean ± SEM of n= 4-8. P ≤ 0.01 (**); P ≤ 0.001 (***).

(A) 7664 is a tissue section from a healthy lung whereas 1015 and 1033 are sections from IPF patients with various advanced degrees of IPF. The panels show representative images mapping the interactive states of GAS6 and PROS1 with AXL (pseudo-colour heat map of (Ef%) on the expression level of GAS6 and PROS1 (fluorescence images in grey scale). The individual violin plots quantify the heterogeneity of interactive states for both ligands and the receptor. The dotted line at 4% Ef represents the Förster Radius (R 0 ). Values below 4% are not representative of ligand-receptor interactions. (B) Global violin plots of all coincident regions (per pixel) of AXL-GAS6 and AXL-PROS1. Each global violin plot represents 2x10 6 data points. To determine the p values for AXL-GAS6 and AXL-PROS1, using non-parametric Mann- Whitney U test, we utilised 1000 randomly generated data points of the 2x10 6 . Healthy lung has similar distribution of AXL-GAS6 and AXL-PROS1 interactions, whereas the two patient samples show, in one case (1015) no interaction of AXL-GAS6 or AXL-PROS1 and another case (1033) a significantly higher distribution of AXL-PROS1 versus AXL-GAS6. The p values between AXL-GAS6 and AXL-PROS1 are 1.9x10 -3 (7664), 2.4x10 -1 (1015) and 8.2x10 - respectively. The dotted line at 4% Ef represents the Förster Radius (R 0 ).

After injury, the normal repair process involves an initial inflammatory response, followed by AXL- GAS6 interaction, which promotes cell proliferation. Once sufficient proliferation is achieved, AXL-PROS1 binding occurs, halting proliferation and triggering cell differentiation. This balance between proliferation and differentiation ensures proper repair, leading to healthy alveoli. However, dysbalanced AXL signaling due to repeated injury and persistently high TGF- ß levels, can result in aberrant repair and irreversible fibrosis (IPF). This may occur due to high-affinity interaction between AXL and GAS6 prevents PROS1 from effectively binding to AXL. As a result, excessive proliferation occurs with insufficient differentiation, leading to aberrant repair and fibrosis. Scheme was created in BioRender. Geillinger-kästle, K.
