Macrophage Polarisation in the Tumour Microenvironment: Recent Research Advances and Therapeutic Potential of Different Macrophage Reprogramming.
Cancer Control
January 2025
Department of Thoracic Surgery, Affiliated Hospital 6 of Nantong University, Medical School of Nantong University, Nantong, PR China.
Background: Macrophages are a critical component of the innate immune system, derived from monocytes, with significant roles in anti-inflammatory and anti-tumour activities. In the tumour microenvironment, however, macrophages are often reprogrammed into tumour-associated macrophages (TAMs), which promote tumour growth, metastasis, and therapeutic resistance.
Purpose: To review recent advancements in the understanding of macrophage polarisation and reprogramming, highlighting their role in tumour progression and potential as therapeutic targets.
A humanized anti-b7h3×4-1BB bispecific antibody exerts potent antitumour effects through the activation of innate and adaptive immunity.

Agonistic monoclonal antibodies targeting 4-1BB have shown much preclinical promise, but their clinical development has been limited by obvious toxicity or unremarkable efficacy. Here, we generated two humanized anti-B7H3 × 4-1BB bsAbs (HK056-001/002) by fusing an anti-4-1BB scFv to the C-terminus of an anti-B7H3 with an intact Fc fragment from human IgG1 or IgG4. The two bsAbs were able to stimulate the 4-1BB signaling pathway, which was strictly dependent on B7H3 expression.

January 2025
Bahrain Defence Force Royal Medical Services, Riffa, Bahrain.
Objective: Tumour-associated macrophages (TAMs) are crucial in the progression and treatment response of oral squamous cell carcinoma (OSCC). TAMs infiltrate OSCC, adopting an M2-like phenotype that promotes tumour growth, metastasis and immune suppression. The current narrative review explored the roles of TAMs in OSCC, focusing on their impact on the tumour microenvironment, invasion, metastasis, angiogenesis, immunosuppression and potential therapeutic targeting.

Department of Pathology, GROW - Research Institute for Oncology and Reproduction, Maastricht University Medical Center+, Maastricht, the Netherlands; Pathology and Data Analytics, Leeds Institute of Medical Research at St. James's, University of Leeds, Leeds, United Kingdom. Electronic address:
Background: Regional lymph node (LN) status is a key prognostic factor in oesophageal cancer (OeC). Tumour-derived antigens can activate immune reactions in LNs, potentially reflecting the host's anti-tumour immune response. It remains unclear whether this response is homogeneous across all tumour negative LNs (LNneg) within individual OeC patients.

Parasitology Research Laboratory, Department of Zoology, Visva-Bharati, Santiniketan-731235.
Quercetin, a vital flavonoid found in many medicinal plants, has shown anti-inflammatory, anti-cancerous, anti-aging, anti-tumour, anti-viral, anti-fungal, anti-bacterial, anti-obesity, anti-diabetic, and anti-protozoal activity. However, very little is known of its anthelmintic activity; there is no literature against tapeworm infection so far. The present study was performed to expose its cestocidal role by using the zoonotic tapeworm as a parasite model.
