Inflammation is an essential component of the immune response that protects the host against pathogens and facilitates tissue repair. Chronic inflammation is a critical factor in cancer development and progression. It affects every stage of tumor development, from initiation and promotion to invasion and metastasis. Tumors often create an inflammatory microenvironment that induces angiogenesis, immune suppression, and malignant growth. Immune cells within the tumor microenvironment interact actively with cancer cells, which drives progression through complex molecular mechanisms. Chronic inflammation is triggered by factors such as infections, obesity, and environmental toxins and is strongly linked to increased cancer risk. However, acute inflammatory responses can sometimes boost antitumor immunity; thus, inflammation presents both challenges and opportunities for therapeutic intervention. This review examines how inflammation contributes to tumor biology, emphasizing its dual role as a critical factor in tumorigenesis and as a potential therapeutic target.

Galectin-10(Gal-10)/CLC(Charcot-Leyden crystal) has been discovered to be related to ECRSwNP characterized by high eosinophilic infiltration. We aimed to investigate the effects of Gal-10 on ECRSwNP. A total of 36 tissue samples were collected, including 11 ECRSwNP samples, 15 non-ECRSwNP samples, and 10 Control samples.

Rheumatoid arthritis (RA) is a chronic autoimmune condition that impacts the immune system, especially through changes in the splenic immune cell system. This review provides an overview of the role of splenocytes in T cell signaling and their immune response in RA patients. The spleen acts as a critical site for the activation and differentiation of splenic immune cells like T cells, B cells, macrophages, dendritic cells, and NK cells.

Prostate cancer and inflammation mechanism are closely related because chronic inflammation causes inflammatory cells to infiltrate into prostatic atrophy areas and proliferative inflammatory atrophy is accepted as the initiator of prostate cancer. The study included 90 patients (28 patients with benign prostatic hyperplasia (BPH), 35 patients with localized prostate cancer (LPCa), and 27 patients with metastatic prostate cancer (MPCa) and 90 healthy controls. Blood samples from 90 patients and 90 healthy people were used to isolate genomic DNA.

Rationale: Inflammation is central to chronic obstructive pulmonary disease (COPD) pathogenesis but incompletely represented in COPD prognostic models. Neutrophil to lymphocyte ratio (NLR) is a readily available inflammatory biomarker.
Objectives: To explore the associations of NLR with smoking status, clinical features of COPD, and future adverse outcomes.

Background: Maternal childhood maltreatment has been associated with higher risk of adverse neurodevelopment in offspring. Chronic systemic inflammation has been associated with childhood maltreatment and has been identified as a gestational risk factor for adverse neurodevelopment in offspring. Thus, inflammation may be a mechanism by which maternal exposure to maltreatment affects offspring neurodevelopment.
