Natural killer cell dysfunction in hepatic alveolar echinococcosis: an under-recognized cytotoxic node in parasite immune escape

Alveolar echinococcosis (AE), caused by the larval stage of Echinococcus multilocularis, is a chronic and infiltrative hepatic helminth infection characterized by tumor-like growth, progressive tissue destruction and long-term host-parasite coexistence…

Pathogen-associated heterogeneity in pulmonary sepsis: from inflammatory phenotypes and transcriptomic endotypes to precision medicine

Sepsis is a heterogeneous syndrome, and pulmonary infection is its commonest source. Pulmonary sepsis carries a particularly high mortality, especially in patients who develop refractory septic shock, yet it is still managed as a single disease. Conven…

Immune-checkpoint blockade and candidate predictive biomarkers in HIV-negative Kaposi sarcoma: current evidence and a practical research framework

Kaposi sarcoma (KS) is a KSHV/HHV-8-driven vascular neoplasm with heterogeneous HIV-negative epidemiological settings. Immune-checkpoint blockade is biologically plausible, but direct clinical evidence remains limited to a small, non-comparative phase …

Dynamic trajectories of sepsis-induced immunoparalysis: from biological mechanisms to precision monitoring and targeted intervention

Sepsis is increasingly recognized as a heterogeneous syndrome in which profound immunosuppression, or immunoparalysis, may coexist with or follow the initial hyperinflammatory response. This state is characterized by impaired host responsiveness to pat…

Hashimoto’s thyroiditis in differentiated thyroid cancer: autoimmune inflammation, immune surveillance, and tumor escape

Hashimoto’s thyroiditis (HT) and differentiated thyroid cancer (DTC) frequently coexist, yet their biological relationship remains paradoxical. In this critical narrative review informed by a structured literature search, we synthesize epidemiological,…

Defense and subversion: multilevel mitochondrial quality control and pathway‑specific mitophagy outcomes in Mycobacterium tuberculosis infection

Tuberculosis, caused by Mycobacterium tuberculosis, remains a leading cause of infectious mortality worldwide, a burden compounded by rising drug resistance. While mitochondria were long dismissed as mere powerhouses, they now function as hubs that int…

From parasite chromatin to host immune reprogramming: linking developmental state, effector regulation, and persistence in Toxoplasma gondii

Toxoplasma gondii establishes persistent infection despite sustained cell-mediated immune pressure, requiring coordinated regulation of parasite development and host immune responses. Parasite developmental states are controlled by sequence-specific tr…
