Melanoma is the most aggressive form of skin cancer and there is a need for the development of effective anti-melanoma therapies as it shows high metastatic ability and low response rate. In addition, it has been identified that traditional phototherapy could trigger immunogenic cell death (ICD) to activate antitumor immune response, which could not only effectively arrest primary tumour growth, but also exhibit superior effects in terms of anti-metastasis, anti-recurrence for metastatic melanoma treatment. However, the limited tumour accumulation of photosensitizers/photothermal agents and immunosuppressive tumour microenvironment severely weaken the immune effects. The application of nanotechnology facilitates a higher accumulation of photosensitizers/photothermal agents at the tumour site, which can thus improve the antitumor effects of photo-immunotherapy (PIT). In this review, we summarise the basic principles of nanotechnology-based PIT and highlight novel nanotechnologies that are expected to enhance the antitumor immune response for improved therapeutic efficacy.

Cancer stem cells (CSCs) are the key drivers of tumorigenesis and relapse. A growing body of evidence reveals the tremendous power of CSCs to directly resist innate and adaptive anti-tumor immune responses. The immunomodulatory property gives CSCs the ability to control the tumor immune microenvironment (TIME).

Killer Cell Lectin Like Receptor D1 (KLRD1) plays a crucial role in antitumor immunity. However, its expression patterns across various cancers, its relationship with patient prognosis, and its potential as an immunotherapy target remain inadequately understood. We analyzed KLRD1 expression across various cancer types using multi-omics data from The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx), and Gene Expression Omnibus (GEO) databases, correlating it with patient prognosis.

Purpose: Tumor-associated macrophages (TAMs) are pivotal immune cells within the tumor microenvironment (TME), exhibiting dual roles across various cancer types. Depending on the context, TAMs can either suppress tumor progression and weaken drug sensitivity or facilitate tumor growth and drive therapeutic resistance. This study explores whether targeting TAMs can suppress the progression of head and neck squamous cell carcinoma (HNSCC) and improve the efficacy of chemotherapy.

Therapeutic human papillomavirus (HPV) DNA vaccine is an attractive option to control existed HPV infection and related lesions. The two early viral oncoproteins, E6 and E7, are continuously expressed in most HPV-related pre- and cancerous cells, and are ideal targets for therapeutic vaccines. We have previously developed an HPV 16 DNA vaccine encoding a modified E7/HSP70 (mE7/HSP70) fusion protein, which demonstrated significant antitumor effects in murine models.
