Bilirubin as a Modulator of WNK1 Protein Signaling: Implications for Neuroinflammatory Diseases

open access: yesAdvanced Science, EarlyView.
ABSTRACT Previously regarded merely as a potentially harmful waste product of heme catabolism, bilirubin has now emerged as a pleiotropic molecule with potent antioxidant, anti‐inflammatory, and hormone‐like properties. Recent findings have revealed protective effects against cardiovascular, metabolic, autoimmune, and neoplastic diseases, as well as ...

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

open access: yesAdvanced 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

AHR in asthma [PDF]

open access: yesThorax, 2002
Peat et al 1 have contributed a helpful review to the debate on techniques for measuring asthma in population studies. However, they have endorsed airway hyperresponsiveness (AHR) while neatly sidestepping the issue of what test they are discussing. Inhaled provocation tests used in epidemiological work have included histamine, methacholine, hypertonic

Endogenous Ceramide 24:1 Constrains Th17‐Driven Neutrophilic Inflammation by Antagonizing EP2 Signaling

open access: yesAdvanced Science, EarlyView.
Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.

Immune Checkpoint Inhibitors and Immunomodulators for Cancer Immunotherapy: Insights Into Resistance and Therapeutic Strategies

open access: yesAdvanced Science, EarlyView.
The schematic diagram illustrates the roles of novel immune checkpoints, immunomodulatory factors, cell death and multimodal technologies in cancer immunotherapy. Abstract Cancer immunotherapy has redefined cancer treatment. However, the molecular and cellular basis of immune evasion and therapeutic resistance remains incompletely understood.
