Can medicinal mushrooms have prophylactic or therapeutic effect against COVID-19 and its pneumonic superinfection and complicating inflammation?

Medicinal mushrooms have documented effects against different diseases, including infections and inflammatory disorders. The related Basidiomycota Agaricus blazei Murill (AbM), Hericium erinaceus (HE), and Grifola frondosa (GF) have been shown to exert antimicrobial activity against viral agents, Gram-positive and Gram-negative bacteria, and parasites in vitro and in vivo. Since the mechanism is immunomodulatory and not antibiotical, the mushrooms should be active against multi-drug resistant microbes as well. Moreover, since these Basidiomycota also have anti-inflammatory properties, they may

Immunosenescence, Physical Exercise, and their Implications in Tumor Immunity and Immunotherapy.

Aging is associated with a decline in immune function, termed immunosenescence, which compromises host defences and increases susceptibility to infections and cancer. Physical exercise is widely recognized for its myriad health benefits, including the potential to modulate the immune system. This review explores the bidirectional relationship between immunosenescence and physical exercise, focusing on their interplay in shaping antitumor immunity. We summarize the impact of aging on innate and adaptive immune cells, highlighting alterations that contribute to immunosenescence and cancer develo

Characterization and treatment outcomes of malignant histiocytoses in a retrospective series of 141 cases in France.

AbstractMalignant histiocytoses (MH) are rare and poorly understood cancers, with no established therapeutic guidelines. We conducted a national retrospective study of MH diagnosed in France between 2000 and 2023. All cases underwent centralized histological review, and several malignant tumors with a stroma highly enriched in histiocytes were excluded. In total, 141 patients were included, with a median age of 62 years (range, 1-87). The cases comprised either primary MH (64%) or MH associated with other hematologic malignancies (36%). Phenotypes corresponded to histiocytic (43%), interdigita

Current status of the diagnosis and treatment of hemophagocytic lymphohistiocytosis in adults.

Hemophagocytic lymphohistiocytosis (HLH) is a syndrome of defective apoptosis, a disruption of the regulatory pathway that terminates immune and inflammatory responses. Fever, cytopenia, splenomegaly, and/or hemophagocytosis are typical findings of this syndrome. HLH can be induced by genetic disorders (familial) or secondary causes. Familial HLH is rare, while secondary causes in adults include infection, autoimmunity, and malignancy. HLH in adults tends to be confused with or misdiagnosed as sepsis, mainly due to similar clinical manifestations and laboratory findings, which make it difficul

The role and mechanisms of mesenchymal stem cells in postoperative cognitive dysfunction via immune network regulation.

Postoperative cognitive dysfunction (POCD) is a common neurological complication in elderly patients after surgery. Its pathophysiology is complex. Neuroinflammation, oxidative stress, and immune imbalance are all involved in this process. These changes can affect postoperative recovery and reduce patients' quality of life. As population aging continues to increase, the prevention and treatment of POCD have become important clinical issues. In recent years, mesenchymal stem cells (MSCs) have attracted attention in neurological diseases because of their immunomodulatory and tissue healing abili

Manipulating Macrophage/Microglia Polarization to Treat Glioblastoma or Multiple Sclerosis.

Macrophages and microglia are implicated in several diseases with divergent roles in physiopathology. This discrepancy can be explained by their capacity to endorse different polarization states. Theoretical extremes of these states are called M1 and M2. M1 are pro-inflammatory, microbicidal, and cytotoxic whereas M2 are anti-inflammatory, immunoregulatory cells in favor of tumor progression. In pathological states, these polarizations are dysregulated, thus restoring phenotypes could be an interesting treatment approach against diseases. In this review, we will focus on compounds targeting ma
