IgG (IgG1, IgG2, IgG3, IgG4), IgM, IgA, IgD, and IgE are the five immunoglobulin subtypes that make up the majority of our immune system. Beneficial effects have been observed on the administration of Ig in diseases like Kawasaki, multiple myositis, chronic inflammatory demyelinating polyneuropathy (CIDP), and immune thrombocytopenia purpura (ITP). The Fc region, FcγRs, and FcRn of the IgG interact to provide both pro- and anti-inflammatory effects. IgM blocks immune-mediated inflammation using N-like glycans. It has been demonstrated that IgM demonstrates its antiinflammatory activity through IgM anti-leukocyte auto-antibodies (IgM-ALA). Since IgA is the second most prevalent and important Ig that operates on the primary objective in the immune system, which exhibits inhibitory signals in the body and generates inflammation in host cells, it plays a critical role in controlling mucosal homeostasis in the gastrointestinal (GI) tract. Additionally, it has been discovered that activating FcαRI boosts cytokine responses at different levels. IgD, a mysterious class of Ig once discovered, has a role in many disorders, including myeloma and Hodgkin's disease. The stability of IgD with development shows a different role, which has an advantage for the host's survival. IgE is mainly associated with many allergic diseases (food allergies), mediates type 1 responses, and has defenses against parasitic infections, which makes it an important parameter for monoclonal antibodies. Studies showed the possible roles of immunoglobulins, from which it came to light that immunoglobulins have their functions as agonists and antagonists in inflammation.</p>","PeriodicalId":10881,"journal":{"name":"Current pharmaceutical biotechnology","volume":null,"pages":null},"PeriodicalIF":2.2,"publicationDate":"2024-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141916305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

TNBC is recognized for the upper reappearance and has a poorer diagnosis compared with rest breast cancer (BC) types. Presently, as such, no targeted therapy is approved for TNBC and treatment options are subjected to chemotherapy and surgery, which have high mortality rates. Hence, the current article focuses on the scenario of TNBC vital pathways and discusses the latest advances in TNBC treatment, including immune checkpoint inhibitors (ICIs), PARP suppressors, and cancer vaccines. Immunotherapy and ICIs, like PD 1 and PD L1 suppressors, displayed potential in clinical trials (CTs). These suppressors obstruct the mechanisms which allow tumor cells to evade the system thereby boosting the body's defense against TNBC. Immunotherapy, either alone or combined with chemotherapy has demonstrated patient outcomes such as increased survival rates and reduced treatment-related side effects. Additionally, targeted therapy approaches include BRCA/2 mutation poly ribose polymerase inhibitors, Vascular Endothelial Growth Factor Receptor (VEGFR) inhibitors, Epidermal growth factor receptor inhibitors, Fibroblast growth factor inhibitors, Androgen Receptor inhibitors, PIK3/AKT/mTOR pathway inhibitors, Cyclin-dependent kinase (CDK) inhibitors, Notch signaling pathway inhibitors, Signal transducer and activator of transcription 3 (STAT3) signaling pathway inhibitors, Chimeric antigen receptor T (CAR-T) cell therapy, Transforming growth factor (TGF) -β inhibitors, Epigenetic modifications (EPM), Aurora Kinase inhibitors and antibody-drug conjugates.

Not only that, but it also plays non-metabolic functions, including the expression of the gene, cell proliferation, cell migration, and tumor angiogenesis in cancer cells. The existing studies have found that microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs) can promote or inhibit the aerobic glycolysis of cancer cells by affecting PKM2, which increases or decrease the risk of cancers and affect the progression of cancers.
