Immunotherapies are methods for treating disease that specifically target or affect immune system cells. Countries' ongoing struggles with a number of new and reemerging diseases, including the most recent global health concern, the SARS-CoV2 pandemic, serve as proof that infectious diseases constitute a serious threat to human health. As a result, various immunotherapeutic strategies are being researched more and more as alternative treatments for infectious diseases, leading to significant advancements in our understanding of the interactions between pathogen and host immunity. The development of curative therapies for human immunodeficiency virus, tuberculosis, malaria, Zika virus, and most recently COVID-19 has strengthened the role of immunotherapeutic approaches in the broader field of disease control, even though it’s most widespread applications are in the treatment of cancer. In the end, the general adoption of immunotherapeutics will depend on their thorough specificity, safety, and cost [1].
Immunotherapies modify immune system elements to find and destroy pathogens or sick host cells, providing protection from disease or easing symptoms. They are divided into two categories based on how they work: passive immunotherapies, which use ex vivo components that are given to patients, and active immunotherapies, which use virulence factors to activate effectors to activate immune memory components in the host. Many strategies have been described and used successfully over the years [2].
Immunotherapeutic innovations used to combat infectious illness. The three main types of immunotherapies described fall into the following groups: (A) T-cell engineering techniques that utilize patient-derived T-cells that have been genetically altered and are briefly grown in vitro to express CARs. Such CAR Tcells enable increased targeting and eradication of sick cells by non-major histocompatibility complex-driven identification of aberrant cells. (B) Strategies like immunizations, which set off an immunological memory response to fight pathogens invading the body, are used to activate lymphocytes [3]. (C) Monoclonal antibodies (mAbs) or ligands that work by carefully controlling the activity of other immune system cells, such as lymphocytes, are used in antibody/ligand-based therapies. These methods include cytokines, BsmAbs, and checkpoint inhibition. Therapeutic mAbs are also utilised to neutralise pathogen- and host-associated surface antigens, toxins, and other antigens that contribute to disease. For their targeted administration, appropriately modified mAbs may potentially be coupled with substances like small molecule poisons.
Cell proliferation, inflammation, immunity, angiogenesis, wound healing, and repair is just a few of the biological processes that cytokines, which are soluble proteins, facilitate intercellular communication for. Using a chimeric antigen receptor, a recently authorised immunotherapeutic strategy involves improving T-cell performance (CAR) [4]. In order to enable MHC-independent T-cell activation, CAR-T cells are designed to express a recombinant receptor, often containing a T-cell specificity determining antibody derivative binding to a specific receptor expressed on targeted cells coupled to a trans membrane signalling domain.
Immunotherapies of viral disease
Vaccines: Plasmid DNA (pDNA) vaccinations or mRNA vaccines are examples of nucleic acid vaccines. When creating mRNA vaccines from modified alphavirus genomes, target antigen-encoding genes are frequently substituted for structural protein-encoding genes while maintaining the RNA replication machinery [5].
CAR T-cell immunotherapy: The extracellular T cell receptor domain of some of the initial CAR T-cells created for HIV envelope protein (Env)-targeted therapy was replaced with CD4 (CD4-CAR). Although the CAR therapy was safe and practicable in clinical studies, it was unable to permanently lower viral burden.
T-cell-based immunotherapies: The relevance and applicability of T-cell-based immunotherapies are currently being intensively researched in light of the need to create more efficient treatment approaches for TB (with or without HIV coinfection).
Cytokine therapy: Different cytokines are being manipulated to change sick states as a result of a greater understanding of their contributions to crucial biological processes [6].
Despite the wide range of approaches available, authorized immunotherapies for use in humans against infectious disease lag behind those available to treat various tumours. Vaccines are the exception. However, improvements in cancer immunotherapy have had a positive impact on immunotherapies for infectious illnesses. The ongoing efforts to develop drugs and vaccines to combat infectious diseases are complicated by a variety of factors, including the diversity of pathogenic species that cause disease, the variety of clinical manifestations of the disease, the variety of surface antigens they express to get around host immunity, and the various survival mechanisms they have evolved. Aiming to get beyond the drawbacks of traditional chemotherapeutics like efficacy, toxicity, and the growing problem of drug resistance, immune-based methods are particularly promising. To ensure sterilization of a disease like TB, which is defined by mycobacteria at various stages of replication, or malaria, which necessitates control measures on multiple levels to prevent infection and spread, this may include a combination of immunotherapeutic approaches along with conventional treatment options.
