Inflammasomes in Cancer Progression and Anti-Tumor Immunity.

The inflammasomes are critical regulators of innate immunity, inflammation and cell death and have emerged as important regulators of cancer development and control. Inflammasomes are assembled by pattern recognition receptors (PRR) following the sensing of microbial- or danger-associated molecular patterns (MAMPs/DAMPs) and elicit inflammation through the oligomerization and activation of inflammatory caspases. These cysteinyl-aspartate proteases cleave the proinflammatory cytokines IL-1β and IL-18 into their biologically active mature form. The roles of the inflammasomes and associated pro-i

Immunodeficiencies in Adults: Key Considerations for Diagnosis and Management.

Immunodeficiencies in adults are increasingly recognized yet often remain underdiagnosed, leading to significant morbidity from recurrent infections, autoimmunity, and malignancy. Both primary immunodeficiencies (PIDs), now known as inborn errors of immunity (IEI), and secondary immunodeficiencies (SIDs) contribute to immune dysfunction in adults. Although SIDs are more common in adults due to factors like medications, malignancies, metabolic disorders, chronic conditions, and protein-losing conditions, IEI-particularly common variable immunodeficiency (CVID)-can also manifest in adulthood wit

Beyond First-Line Immune Checkpoint Inhibitor Therapy in Patients With Hepatocellular Carcinoma.

Until recently, the treatment landscape for hepatocellular cancer (HCC) was dominated by tyrosine kinase inhibitors (TKIs) which offered an overall survival (OS) benefit when used both in the first-and second-line setting compared to best supportive care. However, the treatment landscape has changed with the introduction of immune checkpoint inhibitors (ICIs) for the treatment of HCC with significant improvement in OS and progression free survival reported with combination atezolizumab and bevacizumab compared to sorafenib in the first-line setting. Nonetheless, the response to ICIs is 20-30%

Role of macrophages in the pathogenesis of atopic dermatitis.

Atopic dermatitis (AD) is one of the most common and most intensively studied chronic inflammatory skin diseases. Several cofactors, such as an impaired skin barrier function, modifications of the immune system, and a complex genetic background, direct the course of AD. Within this complex network, macrophages play a pivotal role in enhanced susceptibility to cutaneous infections and act as central connecting components in the pathogenesis of AD on the cellular level. In AD, macrophages are known to accumulate in acutely and chronically inflamed skin. During the early and short inflammatory ph

NUPR1 Promotes Radioresistance in Colorectal Cancer Cells by Inhibiting Ferroptosis.

Radioresistance is a major clinical challenge and the underlying mechanism has not been thoroughly elucidated. In this study, a radioresistant (RR) cell line is established to explore the transcriptomic signatures of radioresistance in colorectal cancer (CRC). KEGG enriched pathway analysis demonstrated that ferroptosis is inactivated in RR cells. Further detection confirmed that radiotherapy can promote ferroptosis, and ferroptosis inactivation is one of the hallmarks of radioresistance in CRC. What's more, induction of ferroptosis can restore the radiosensitivity of CRC cells. Then, we perfo

Molecular factors associated with lung cancer in people living with HIV.

Lung cancer is the most common Non-AIDS-Defining Cancer (NADC) and a leading cause of cancer-related death in People Living With HIV (PLWH). Despite antiretroviral therapy, PLWH are at higher risk of developing cancer compared to the general population. This increased susceptibility reflects a combination of immunosuppression, chronic inflammation, smoking, and direct oncogenic effects of HIV proteins. Tat, gp120, and Nef modulate cell cycle control, apoptosis, epithelial-mesenchymal transition, angiogenesis, and immune evasion. Persistent HIV reservoirs in lung tissue (mainly effector memory

Understanding Autoimmunity: Mechanisms, Predisposing Factors, and Cytokine Therapies.

Autoimmunity refers to an organism's immune response against its own healthy cells, tissues, or components, potentially leading to irreversible damage to vital organs. Central and peripheral tolerance mechanisms play crucial roles in preventing autoimmunity by eliminating self-reactive T and B cells. The disruption of immunological tolerance, characterized by the failure of these mechanisms, results in the aberrant activation of autoreactive lymphocytes that target self-tissues, culminating in the pathogenesis of autoimmune disorders. Genetic predispositions, environmental exposures, and immun

Resveratrol Nanoformulations for Cancer Management: A Comprehensive Review of Disease-Specific Strategies and Clinical Translational Barriers.

Cancer remains a leading cause of mortality worldwide, highlighting the need for therapeutic strategies that reduce systemic toxicity and drug resistance. Resveratrol (RES), a natural polyphenolic stilbenoid, possesses antioxidant, anti-inflammatory, pro-apoptotic, anti-metastatic, and chemosensitizing activities. However, its clinical translation is limited by poor aqueous solubility, chemical instability, rapid metabolic clearance, and consequently low systemic bioavailability. Nanotechnology-based drug delivery systems provide a promising strategy to address these limitations. This review s

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
