Injectable supramolecular hydrogel co-loading abemaciclib/NLG919 for neoadjuvant immunotherapy of triple-negative breast cancer

Nature Communications
The efficacy of cancer immunotherapy relies on a sufficient amount of functional immune cells. Triple-negative breast cancer lacks enough immune cell infiltration, and adjuvant therapy is necessary to prime anti-tumor immunity.

T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

Structure–activity relationship studies of 5-(Pyridin-3-yl)-1H-indole-4,7-diones as indoleamine 2,3-dioxygenase 1 inhibitors

Results in Chemistry
Indoleamine 2,3-dioxygenase 1 (IDO1) is the key enzyme that catalyzes the conversion of l-tryptophan (Trp) to N-formyl-kynurenine in the tryptophan-kynurenine (Trp-Kyn) pathway.

Indoleamine-2,3-Dioxygenase Mediates Emotional Deficits by the Kynurenine/Tryptophan Pathway in the Ethanol Addiction/Withdrawal Mouse Model

Frontiers in Cellular Neuroscience, 2020
ObjectiveOur study was designed to investigate whether the indoleamine-2,3-dioxygenase (IDO)-mediated kynurenine/tryptophan (KYN/TRP) pathway participates in the development of emotional deficits from ethanol addiction/withdrawal mice.MethodsThe ...

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

British Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

The FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

Indoleamine 2,3‐Dioxygenase 1 as an Adjunctive Histopathological Marker of Cholangitis Activity in Primary Biliary Cholangitis

Hepatology Research, EarlyView.
IDO‐1 immunostaining identifies primary biliary cholangitis even in morphologically subtle bile duct lesions. IDO‐1 expression reflects cholangitis activity and is suppressed by ursodeoxycholic acid treatment, indicating its value as a dynamic diagnostic adjunct rather than a static marker of chronic damage.

Hyaluronic Acid Modulates IL1β‐Induced Cytokine Profile of Gingival Mesenchymal Stem Cells

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim Hyaluronic acid (HA) possesses anti‐inflammatory properties critical for periodontal wound healing. In this study, we aimed to evaluate the role of cross‐linked high‐molecular‐weight (HMW) HA on cytokine mRNA expression, cell viability and migration in IL‐1β‐stimulated gingival mesenchymal stem cells (gMSCs).

Induction of indoleamine 2,3-dioxygenase in primary human macrophages by HIV-1

Redox Report, 2000
Increased kynurenine pathway metabolism has been implicated in the aetiology of the AIDS dementia complex (ADC). The rate limiting enzyme for this pathway is indoleamine 2,3-dioxygenase (IDO). We tested the efficacy of different strains of HIV-1 (HIV1-BaL, HIV1-JRFL and HIV1-631) to induce IDO in cultured human monocyte-derived macrophages (MDM).
