An in situ depot for the sustained release of a TLR7/8 agonist in combination with a TGFβ inhibitor promotes anti-tumor immune responses.

Cancer curing immune responses against heterogeneous solid cancers require that a coordinated immune activation is initiated in the antigen avid but immunosuppressive tumor microenvironment (TME). The plastic TME, and the poor systemic tolerability of immune activating drugs are, however, fundamental barriers to generating curative anticancer immune responses. Here, we introduce the CarboCell technology to overcome these barriers by forming an intratumoral sustained drug release depot that provides high payloads of immune stimulatory drugs selectively within the TME.

HER2-targeted, enzyme-activated liposomes show superior in vivo efficacy in an ovarian cancer model.

Liposomes carrying chemotherapeutic drugs can accumulate passively in solid tumors at high levels. However, additional targeting of the liposomes towards e.g.

Diagnostic Workup, Treatment Patterns, and Clinical Outcomes in Early-Stage IB-IIIA Non-Small-Cell Lung Cancer Patients in Denmark.

Despite recent improvements in early-stage non-small-cell lung cancer (NSCLC), disease relapse remains challenging. Moreover, real-world evidence on long-term follow-up of disease-free survival (DFS) and recurrence patterns in a large, unselected cohort of early-stage NSCLC patients is lacking. This cohort study aimed to assess clinical characteristics, diagnostic workup, treatment, survival, and risk of disease relapse among early-stage NSCLC patients.

Cell surface-tethered IL-12 repolarizes the tumor immune microenvironment to enhance the efficacy of adoptive T cell therapy.

Immune-activating cytokines such as interleukin-12 (IL-12) hold strong potential for cancer immunotherapy but have been limited by high systemic toxicities. We describe here an approach to safely harness cytokine biology for adoptive cell therapy through uniform and dose-controlled tethering onto the surface of the adoptively transferred cells. Tumor-specific T cells tethered with IL-12 showed superior antitumor efficacy across multiple cell therapy models compared to conventional systemic IL-12 coadministration.

In vivo detection of urokinase-type plasminogen activator receptor (uPAR) expression in arterial atherogenesis using [Cu]Cu-DOTA-AE105 positron emission tomography (PET).

Background And Aims: Urokinase-type plasminogen activator receptor (uPAR) is associated with extracellular matrix (ECM) degradation and cancer aggressiveness. Its role in arterial atherogenesis as a molecular imaging target is not well-established. The aim of this study was to non-invasively visualize uPAR expression in atherosclerosis by a novel uPAR-targeting positron emission tomography (PET) tracer [Cu]Cu-DOTA-AE105.

Matrix effect in tumor lysates - Does it affect your cytokine ELISA and multiplex analyses?

Quantification of cytokines in cancerous tissue is important for understanding basic tumor biology and for deciphering anti-cancer mechanisms in drug development. Cytokine measurements on protein-level are often done by immunoassays such as enzyme-linked immunosorbent assay (ELISAs) and multiplex assays. However, immunoassays are prone to interference due to the presence of perturbing factors.

Flow Cytometric Evaluation of the Ongoing Angiogenic Response in Rat Cardiac Tissue Following Myocardial Infarction.

Angiogenesis is involved in regeneration of cardiac tissue following acute myocardial infarction (MI), a disease often investigated in rat models. Therefore, the ability to thoroughly evaluate the angiogenic response following experimentally induced MI in rats, and distinguish it from inflammation, is desired. This would enable evaluation of the angiogenic potential of new therapeutics and improve knowledge on MI pathophysiology.

Effect of apoA-I PEGylation on the Biological Fate of Biomimetic High-Density Lipoproteins.

Biomimetic high-density lipoproteins (b-HDL) have in the past two decades been applied for various drug delivery applications. As b-HDL inherently have relatively long circulation half-life and high tumor accumulation, this has inspired researchers to use b-HDL to selectively deliver drugs to tumors. PEGylation of the b-HDL has been pursued to increase the circulation half-life and therapeutic efficacy even further.
