SIRPα blockade therapy potentiates immunotherapy by inhibiting PD-L1+ myeloid cells in hepatocellular carcinoma

open access: yesCell Death and Disease
Tumor-infiltrating myeloid cells (TIMs) are pivotal cell populations involved in the immunosuppressive tumor immune microenvironment (TIME). However, there has been little success in large-scale clinical trials of myeloid cell modulators.

In Vivo Immunoscoring Technique to Monitor Anti‐CD47 Immunotherapy Efficacy in Triple‐Negative Breast Cancer

open access: yesCancer Medicine, Volume 15, Issue 10, October 2026.
Intravital imaging using MCP1‐FITC and dextran‐AF680 assesses macrophage targeting and polarization in murine 4T1 tumor models. Visualization of M1‐like and M2‐like macrophages and M1/M2 ratio quantification support evaluation of anti‐CD47 immunotherapy, highlighting the potential of macrophage‐targeted imaging for patient stratification and treatment ...

Phase 1 dose escalation and expansion trial of the bispecific CD47 inhibitor and CD40 agonist Fc‐fusion protein SL‐172154 (SIRPα‐Fc‐CD40L) in patients with higher‐risk myelodysplastic syndrome or acute myeloid leukemia

open access: yesCancer, Volume 132, Issue 19, 1 October 2026.
Abstract Background This clinical trial sought to determine whether SL‐172154 could be combined safely and improve the efficacy of azacitidine (AZA) in patients with higher‐risk myelodysplastic syndrome (HR‐MDS) or acute myeloid leukemia (AML). Methods Dose escalation: doses of 1, 3, and 6 mg/kg SL‐172154 was evaluated as monotherapy or in combination ...

Development of Fully Human Antibodies Targeting SIRPα and PLA2G7 for Cancer Therapy

open access: yesAntibodies
Background: Macrophages play an important role in eliminating diseased and damaged cells through programmed cell death. Signal regulatory protein alpha (SIRPα) is a crucial immune checkpoint primarily expressed on myeloid cells and macrophages.

PANoptosis In Microglia and Neurons Following Traumatic CNS Injury: A Systematic Review of Pathological Features and Therapeutic Implications

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 10, October 2026.
Following traumatic CNS injury, PANoptosis is activated in microglia and neurons, with microglia–neuron crosstalk serving as a key feature of this process. The PANoptosome sensors ZBP1 and NLRP12, together with the adaptor ASC, activate downstream executioner proteins to drive PANoptosis.

Investigating CD8 T Cell Exhaustion in Chronic LCMV Infection by Flow Cytometry

open access: yesCurrent Protocols, Volume 6, Issue 10, October 2026.
Abstract CD8 T cells and the process of T cell exhaustion are central topics in both basic immunology and translational research, including clinical applications. Here, we provide a comprehensive, step‐by‐step guide to investigate CD8 T cells in murine in vivo lymphocytic choriomeningitis virus (LCMV) infection models.

A human antibody specific for SIRPα reprograms macrophages and promotes antibody mediated anti-cancer activity.

open access: yesPLoS ONE
Several T cell immune checkpoint blockade therapies have shown initial successes in multiple cancers. However, significant issues remain, including tumor relapse, severe toxicities, and a lack of efficacy in most patients.

CLDN18.2 in pancreatic ductal adenocarcinoma: Biomarker assessment, spatial heterogeneity and therapeutic modality selection

open access: yesClinical and Translational Discovery, Volume 6, Issue 5, October 2026.
This review presents a framework for selecting Claudin 18.2 (CLDN18.2)‐directed treatment modalities in pancreatic ductal adenocarcinoma according to tumour antigen coverage and spatial distribution. Representative assessment at baseline and reassessment after progression can guide treatment adaptation over time.

Signal regulatory protein α dynamically mediates macrophage polarization facilitated alleviation of ischemic diseases

open access: yesCell & Bioscience
Background macrophage-targeting therapy of ischemic disease has made progress in clinic trial. However, the role and underlying mechanism of pro-inflammatory or anti-inflammatory polarized macrophages in modulating ischemic diseases remain incompletely ...

Context‐dependent TREM2 signalling in myeloid cells: Molecular mechanisms and immunotherapeutic divergence in neurodegeneration and cancer

open access: yesClinical and Translational Medicine, Volume 16, Issue 10, October 2026.
Divergent triggering receptor expressed on myeloid cells 2 (TREM2) signalling pathways instruct myeloid cell adaptation towards neuroprotective disease‐associated microglia (DAM)/lipid‐associated macrophage (LAM) or immunosuppressive tumour‐associated macrophage (TAM) phenotypes.
