    Schematic diagram of our major findings. Pro-differentiation factors, such as PMA, M-CSF, and thioglycollate, upregulate Flrt2 expression in monocytes. FLRT2, in turn, accelerates monocyte-to-macrophage differentiation by binding to UNC5B via its ECD and subsequently activating the Akt/mTOR signaling pathway.

    Figure Lengend Snippet: The direct interaction of the FLRT2 ECD with UNC5B is required for FLRT2-promoted THP-1 cell differentiation into macrophages. (A) Myc-tagged hUNC5B and/or Flag-tagged hFLRT2 were transfected into HEK293T cells. Immunoprecipitation samples were collected using anti-Flag antibody, followed by immunoblotting for Myc and Flag (n = 3). (B) Immunolabeling of FLRT2 and UNC5B in PMA-treated THP-1 cells showing the colocalization of endogenous UNC5B and FLRT2. Scale bar, 10 μm. (C) UNC5B was immunoprecipitated from PMA-incubated THP-1 cells, followed by immunoblotting for FLRT2 and UNC5B (n = 3). (D) Schematic illustration of FLRT2 and UNC5B constructs. LRRNT, leucine-rich repeat N-terminal domain. LRR, leucine-rich repeat. LRRCT, leucine-rich repeat C-terminal domain. FNIII, fibronectin type III domain.

    FLRT2 activates Akt/mTOR signaling via the binding of UNC5B with Rac1. (A) Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis of the upregulated differentially expressed genes (DEGs) in PMs of Flrt2 fl/fl and Flrt2 ΔMyel mice. (B) Immunoblot analysis of p-Akt (Ser473), p-Akt (Thr308), Akt, p-mTOR (Ser2481), mTOR, p-4E-BP-1 (Thr37/46), 4E-BP-1, p-S6K (Thr389), S6K, p-S6 (Ser240/244), and S6 proteins in PMs isolated from Flrt2 fl/fl and Flrt2 ΔMyel mice i.p. injected with thioglycollate for 3 days (n = 3 mice per group).

(E) Immunoprecipitation samples were collected using anti-Flag antibody from control vector and Flag-UNC5B-overexpressing HEK293T cells and subjected to mass spectrometry (MS) to identify potential binding partners of UNC5B protein. A unique peptide of Rac1 protein was identified in the UNC5B-overexpressing immunoprecipitation samples by analyzing the mass-to-charge ratio of the samples. (F) The endogenous interaction between Rac1 and UNC5B was confirmed in THP-1 cells by co-immunoprecipitation (co-IP) analysis. Data are means ± SD. P values were determined using unpaired, two-tailed Student’s t -tests. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001.

    Schematic diagram of our major findings. Pro-differentiation factors, such as PMA, M-CSF, and thioglycollate, upregulate Flrt2 expression in monocytes. FLRT2, in turn, accelerates monocyte-to-macrophage differentiation by binding to UNC5B via its ECD and subsequently activating the Akt/mTOR signaling pathway.
