This review provides an overview of the advantages and limitations of the main proteins that have been proposed as biomaterials for nanoparticle fabrication, with a specific focus on albumin-based systems. It explores the physicochemical characteristics of these nanosystems, receptor binding affinity and functionalization strategies for both passive and active tumor targeting. The main synthesis methods and functionalization strategies are discussed, highlighting their relevance in cancer therapy. Their clinical relevance is stressed by the US Food and Drug Administration (FDA)-approved formulations and the additional albumin-bound drugs in ongoing trials. Despite promising preclinical data and numerous active targeting approaches reported, clinical translation remains limited.

Briefly, SRN reshaped TAMs <em>in situ</em> relying on tissue tropism of macrophage membrane, firstly upregulating their reactive oxygen species (ROS) production <em>via</em> burst release of Spark element and initially shifting the TAMs into the anti-tumoral phenotype, subsequently elevating NO production by releasing Relay element, which is converted to NO <em>via</em> reaction with ROS and iNOS, leading to the generation of additional ROS and creating a positive feedback loop, thereby strengthening the metabolic rewiring of TAMs from passively defensive oxidative phosphorylation to positively offensive glycolysis, which significantly enhanced the antitumoral activity of TAMs and shrunk tumor immunosuppressive microenvironment, emerging as 5.5-fold increase of tumor-suppressive/supportive ratio (TSSR) of TAMs, 4.0-fold elevation of CD8<sup>+</sup> T cell infiltration, contributing to a satisfactory tumoricidal efficacy and providing a cascade amplification mode for TAMs-based cancer therapeutics.</div></div>","PeriodicalId":6906,"journal":{"name":"Acta Pharmaceutica Sinica.

As a potential solution, non-invasive and targeted drug delivery at mucosal surfaces can deliver drugs directly to therapeutic sites to avoid off-target effects, decrease required drug doses, bypass hepatic first-pass metabolism, and circumvent uncontrolled drug release. Liquid-based drug delivery systems have advanced tremendously over recent years, with novel dosage forms such as ionic liquids, liquid crystals, stimuli-responsive phase transforming liquid systems, nanoemulsions, double-emulsions, self-emulsifying delivery systems, and eutectic systems being developed. These systems hold vast promise for transmucosal drug delivery as liquids generally provide superior spreadability compared to solid dosage forms, and some liquid systems provide prolonged mucosal retention times compared to conventional solutions. However, liquid dosage forms present regulatory challenges such as preservation, sterility, and stability requirements.

Isoalantolactone (IAL), a naturally occurring small molecule, has been identified herein to inhibit cytosolic thioredoxin reductase1 (TXNRD1) and trigger pyroptosis in AML cells, thereby enhancing the efficacy of anti-PD-1 antibody therapy. Mechanistically, the <em>α</em>,<em>β</em>-unsaturated carbonyl group of IAL covalently bound to the selenocysteine residue at the position 498 (Sec<sup>498</sup>) of TXNRD1 through a Michael addition reaction. Clinical sample analysis revealed that TXNRD1 is overexpressed in AML, which correlates with poor prognosis. Additionally, we found that the TXNRD inhibitor auranofin has demonstrated good efficacy against AML. The inhibition of TXNRD1 activates the transcription factor peroxisome proliferator-activated receptor gamma (PPAR<em>γ</em>), which, in turn, upregulates the transcription of caspase-3, subsequently increasing the cleavage of gasdermin E to induce pyroptosis <em>via</em> the non-classical pathway in AML cells. Additionally, enhanced caspase-3 activity promotes poly ADP-ribose polymerase 1 (PARP-1) cleavage and upregulates PD-L1 expression, thereby increasing sensitivity to anti-PD-1 monoclonal antibodies. Overall, the current study highlights a promising approach for augmenting therapy using anti-PD-1 monoclonal antibodies in AML by targeting TXNRD1 to induce pyroptosis and ameliorate the immunosuppressive microenvironment.</div></div>","PeriodicalId":6906,"journal":{"name":"Acta Pharmaceutica Sinica.
