AI Article Synopsis
- LAPTM4B is a gene found on chromosome 8q22 that plays a role in cancer and is made up of seven exons and six introns, producing two protein isoforms: LAPTM4B-35 and LAPTM4B-24.
- LAPTM4B-35 is significantly upregulated in several cancers, while LAPTM4B-24 is downregulated, and LAPTM4B-35 has a longer N-terminal compared to LAPTM4B-24.
- Research using techniques like western blotting found that the N91 region of LAPTM4B-35 is expressed in various tissues, but its weak immunogenicity indicates it may not be a strong candidate for tumor-associated antigen
Article Abstract
Lysosome-associated protein transmembrane 4β (LAPTM4B) is a gene that has been indicated to be involved in cancer. It is located at chromosome 8q22 and is composed of seven exons and six introns. LAPTM4B encodes two protein isoforms: LAPTM4B-35 and LAPTM4B-24. LAPTM4B-35 is markedly upregulated and LAPTM4B-24 is downregulated in several types of cancer. LAPTM4B-35 is 91 amino acids (N91) longer than LAPTM4B-24 at the N-terminus. In the present study, western blotting, enzyme-linked immunosorbent spot analysis and the B16F10-N91 tumor bearing-mice experiments were used to evaluate whether the overexpression of N91 indicates its potential as a candidate tumor-associated antigen. The results revealed that N91 was expressed in a wide range of normal mouse tissues and human peripheral blood mononuclear cells, with varying expression levels. The weak immunogenicity of N91 protein suggested it was a weak candidate antigen; however, the N91 protein was associated with cell proliferation.

Glioblastoma (GBM), the most malignant brain tumor with high prevalence, remains highly resistant to the existing immunotherapies due to the significant immunosuppression within tumor microenvironment (TME), predominantly manipulated by M2-phenotypic tumor-associated macrophages (M2-TAMs). Here in this work, an M2-TAMs targeted nano-reprogrammers, MG5-S-IMDQ, is established by decorating the mannose molecule as the targeting moiety as well as the toll-like receptor (TLR) 7/8 agonist, imidazoquinoline (IMDQ) on the dendrimeric nanoscaffold. MG5-S-IMDQ demonstrated an excellent capacity of penetrating the blood-brain barrier (BBB) as well as selectively targeting M2-TAMs in the GBM microenvironment, leading to a phenotype transformation and function restoration of TAMs shown as heightened phagocytic activity toward tumor cells, enhanced cytotoxic effects, and improved tumor antigen cross-presentation capability.

Thoracic malignancies (lung cancers and malignant pleural mesothelioma) are prevalent worldwide and are associated with high morbidity and mortality. Effective treatments are needed for patients with advanced disease. Cell therapies are a promising approach to the treatment of advanced cancers that make use of immune effector cells that have the ability to mediate antitumor immune responses.

The discovery of tumor-derived neoantigens which elicit an immune response through major histocompatibility complex (MHC-I/II) binding has led to significant advancements in immunotherapy. While many neoantigens have been discovered through the identification of non-synonymous mutations, the rate of these is low in some cancers, including head and neck squamous cell carcinoma. Therefore, the identification of neoantigens through additional means, such as aberrant splicing, is necessary.

Paraneoplastic cerebellar degeneration (PCD) is a rapidly progressive, immune-mediated syndrome characterized by the degeneration of Purkinje cells, often associated with the presence of antibodies targeting intracellular antigens within these cells. These autoantibodies are implicated in the induction of cytotoxicity, leading to Purkinje cell death, as demonstrated in in vitro models. However, the precise roles of antibodies and T lymphocytes in mediating neuronal injury remain a subject of ongoing research, with T cells appearing to be the main effectors of cerebellar injury.
