    Schematic illustration of in vivo tumor immunotherapy enhanced by mRNA/HNPs through intravenous injection. H18 lipid, DOPE, cholesterol, DMG-PEG 2000 and mRNA were mixed to form mRNA/H 18 NPs with the special multilamellar concentric nanostructures. Following intravenous administration, mRNA/H 18 NPs demonstrated preferential adsorption of <t>complement</t> <t>C3</t> proteins to form a characteristic protein corona, resulting in specific mRNA transfection in the spleen, especially in splenic dendritic cells. When encapsulating tumor antigen-encoding mRNA, the mRNA/H 18 NPs achieved precise transfection of the antigen mRNA in splenic dendritic cells. This targeted delivery stimulated dendritic cell maturation and subsequent antigen presentation, initiating robust T cell priming. The activated antigen-specific cytotoxic T lymphocytes then infiltrated into tumor tissues, ultimately inducing tumor cell elimination.

    (A) The impact of OMVs on germicidal activity of serum against YeO3‐c bacteria. The influence of OMVs‐associated with: LPS polysaccharide chain length (a) and pYV‐coded factors (b). Data from one of at least two experiments with the use of separately prepared culture supernatants with similar results are presented. 1 sterile cell culture supernatants (secreted by bacteria grown to OD 600 = 0.6) were used as a source of OMVs; 2 expression at 37°C only; 3 NHS inactivated 30 min at 56°C. (B) Y. enterocolitica O:3 OMV‐induced complement activation in the presence of calcium and magnesium chelators. ELISA plates were coated with 10 8 of OMVs secreted by YeS‐c bacteria grown at 4°C, 22°C and 37°C and with OMVs of YeRa‐c, YeRd1‐c and YeRe‐c variants propagated at 37°C. After incubation with/without EDTA, EGTA or EGTA/Mg 2+ (EGTA supplemented with Mg 2+ ions), products of <t>C3</t> activation were detected with <t>specific</t> <t>antibodies.</t> Data from one of two experiments with similar results are presented. (C) Comparison of complement activation and MBL binding by Yersinia enterocolitica O:3 bacterial cells, LPS and OMVs. ELISA plates were coated with 50 ng/well of bacteria, LPS or OMVs. The deposition of C3 (a, possible AP, CP and LP involvement), C4 (b, possible CP and LP involvement) or C4 LP‐dependent (d) activation products, TCC formation (c, possible AP, CP and LP involvement) and MBL‐binding (e) was analyzed after preincubation with normal human serum (filled columns) or with EDTA‐treated NHS (stripped columns) or without serum (open columns, negative control). Data from one of two experiments with similar results are presented. Dots represent individual OD values for each well. (D) Recognition of Y. enterocolitica O:3 OMVs by human mannose‐binding lectin. YeS‐c_37°C bacteria (1), OMVs (2) and LPS (3) were separated in SDS‐PAGE. After transfer to nitrocellulose and incubation with NHS, the bound MBL was detected with specific mAb (a). The experiment was performed at least 5 times. To control the loading of bacteria, LPS or OMVs the presence of OPS in separated samples was confirmed with anti‐6‐deoxy‐L‐altropyranose mAbs (b).

    (A) The impact of OMVs on germicidal activity of serum against YeO3‐c bacteria. The influence of OMVs‐associated with: LPS polysaccharide chain length (a) and pYV‐coded factors (b). Data from one of at least two experiments with the use of separately prepared culture supernatants with similar results are presented. 1 sterile cell culture supernatants (secreted by bacteria grown to OD 600 = 0.6) were used as a source of OMVs; 2 expression at 37°C only; 3 NHS inactivated 30 min at 56°C. (B) Y. enterocolitica O:3 OMV‐induced complement activation in the presence of calcium and magnesium chelators. ELISA plates were coated with 10 8 of OMVs secreted by YeS‐c bacteria grown at 4°C, 22°C and 37°C and with OMVs of YeRa‐c, YeRd1‐c and YeRe‐c variants propagated at 37°C. After incubation with/without EDTA, EGTA or EGTA/Mg 2+ (EGTA supplemented with Mg 2+ ions), products of <t>C3</t> activation were detected with <t>specific</t> <t>antibodies.</t> Data from one of two experiments with similar results are presented. (C) Comparison of complement activation and MBL binding by Yersinia enterocolitica O:3 bacterial cells, LPS and OMVs. ELISA plates were coated with 50 ng/well of bacteria, LPS or OMVs. The deposition of C3 (a, possible AP, CP and LP involvement), C4 (b, possible CP and LP involvement) or C4 LP‐dependent (d) activation products, TCC formation (c, possible AP, CP and LP involvement) and MBL‐binding (e) was analyzed after preincubation with normal human serum (filled columns) or with EDTA‐treated NHS (stripped columns) or without serum (open columns, negative control). Data from one of two experiments with similar results are presented. Dots represent individual OD values for each well. (D) Recognition of Y. enterocolitica O:3 OMVs by human mannose‐binding lectin. YeS‐c_37°C bacteria (1), OMVs (2) and LPS (3) were separated in SDS‐PAGE. After transfer to nitrocellulose and incubation with NHS, the bound MBL was detected with specific mAb (a). The experiment was performed at least 5 times. To control the loading of bacteria, LPS or OMVs the presence of OPS in separated samples was confirmed with anti‐6‐deoxy‐L‐altropyranose mAbs (b).

    Schematic illustration of in vivo tumor immunotherapy enhanced by mRNA/HNPs through intravenous injection. H18 lipid, DOPE, cholesterol, DMG-PEG 2000 and mRNA were mixed to form mRNA/H 18 NPs with the special multilamellar concentric nanostructures. Following intravenous administration, mRNA/H 18 NPs demonstrated preferential adsorption of complement C3 proteins to form a characteristic protein corona, resulting in specific mRNA transfection in the spleen, especially in splenic dendritic cells. When encapsulating tumor antigen-encoding mRNA, the mRNA/H 18 NPs achieved precise transfection of the antigen mRNA in splenic dendritic cells. This targeted delivery stimulated dendritic cell maturation and subsequent antigen presentation, initiating robust T cell priming. The activated antigen-specific cytotoxic T lymphocytes then infiltrated into tumor tissues, ultimately inducing tumor cell elimination.
