In Brief: Myeloid-derived suppressor cells in cancer [PDF]

, 2017
The role of myeloid-derived suppressor cells (MDSCs) in cancer development has become clear over recent years, and MDSC targeting is an emerging opportunity for enhancing the effectiveness of current anticancer therapies.

O‐GlcNAcylated TAP1 Impairs Antigen Presentation and Promotes Immune Evasion in Bladder Cancer

Advanced Science, EarlyView.
This article unveils a critical mechanism of immune evasion in bladder cancer, which the O‐GlcNAc modification of TAP1 disrupts antigen presentation. This modification triggers HLA‐A degradation, shielding tumor cells from CD8+ T cell attack. The findings highlight targeting this pathway as a promising therapeutic avenue to sensitize tumors to ...

Ferumoxytol Attenuates the Function of MDSCs to Ameliorate LPS-Induced Immunosuppression in Sepsis

Nanoscale Research Letters, 2019
Sepsis-induced immunosuppression is recognized as one of the main features responsible for therapeutic failures. Myeloid-derived suppressor cells (MDSCs), which are mainly characterized by their suppressive properties, have been reported to be expanded ...

Androgen Receptor‐Induced Lactoferrin Accelerates Prostate Tumorigenesis Through Modulating Ferroptosis

Advanced Science, EarlyView.
This study demonstrates that transcription factor androgen receptor (AR) directly binds the LF promoter, driving lactoferrin overexpression to promote ferritin (FTH1/FTL) upregulation and inhibit p53‐ALOX12‐mediated ferroptosis in prostate cancer. Lactoferrin could be a new potential therapeutic target in prostate cancer.

The tumour microenvironment links complement system dysregulation and hypoxic signalling. [PDF]

, 2018
The complement system is an innate immune pathway typically thought of as part of the first line of defence against "non-self" species. In the context of cancer, complement has been described to have an active role in facilitating cancer-associated ...

Targeting m6A Reader YTHDF1 Enhances Antitumor Immunity and Potentiates Anti‐PD‐L1 Efficacy in Intrahepatic Cholangiocarcinoma

Advanced Science, EarlyView.
The m6A reader YTHDF1 drives intrahepatic cholangiocarcinoma (ICC) progression by remodeling the tumor immune microenvironment. YTHDF1 promotes MDSC recruitment via activation of m6A‐FOSL2‐CXCL6/CXCR2 axis, thereby suppressing CD8+ T cell infiltration and function.

Myeloid-Derived Suppressor Cells Impair Alveolar Macrophages through PD-1 Receptor Ligation during Pneumocystis Pneumonia [PDF]

, 2015
Myeloid-derived suppressor cells (MDSCs) were recently found to accumulate in the lungs during Pneumocystis pneumonia (PcP). Adoptive transfer of these cells caused lung damage in recipient mice, suggesting that MDSC accumulation is a mechanism of ...

Macrophage Extracellular Traps in Immunity and Cancer

Advanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.

Activation of mTOR pathway in myeloid-derived suppressor cells stimulates cancer cell proliferation and metastasis in lal(-/-) mice [PDF]

, 2014
Inflammation critically contributes to cancer metastasis, in which myeloid-derived suppressor cells (MDSCs) are an important participant. Although MDSCs are known to suppress immune surveillance, their roles in directly stimulating cancer cell ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome
