Sequencing of the mycobacterial genome revealed that 10% of its coding ability is devoted to the Pro-Glu motif-containing (PE) and Pro-Pro-Glu motif-containing (PPE) family proteins. While the function of most of the genes belonging to the PE-PPE family initially remained unannotated, recent studies have shown that many proteins of this family play critical roles in bacterial growth and cell functions, and manipulation of host immune responses, indicating their potential roles in mycobacterial virulence. In this review, we have focussed on describing the immunological importance of particularly the PE group of proteins in the context of 'virulence' determinants and outcome of tuberculosis disease. Additionally, we have discussed about the roles of these proteins on host-pathogen-interaction and how some of these genes can be targeted which may help us in designing effective anti-TB therapeutics.</p>","PeriodicalId":14333,"journal":{"name":"International Reviews of Immunology","volume":" ","pages":"1-16"},"PeriodicalIF":4.3,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143074664","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}

Consequently, the examination of tumor metabolic heterogeneity, including an exploration of immunometabolism, proves indispensable for enhancing prognostic tools and advancing the quest for personalized treatments. Here we have delved into how metabolic reprogramming profoundly influences the acquisition and maintenance of functional states, spanning from effector and cytotoxic profiles to regulatory and immunosuppressive phenotypes in both innate and adaptive immunity.

However, despite the widespread success of vaccination programs, there are still certain population groups who struggle to mount adequate responses to immunization. These at-risk groups include but are not restricted to the elderly, overweight individuals, individuals with chronic infections and cancer patients. All of these groups are characterized by persistent chronic inflammation. Recent studies have demonstrated that one of the key players in immune regulation and the promotion of chronic inflammation are myeloid-derived suppressor cells (MDSCs). These cells possess a wide range of immunosuppressive mechanisms and are able to dampen immune responses in both antigen-specific and antigen-nonspecific manner, thus contributing to the establishment and maintenance of an inflammatory environment. Given their pivotal role in immune modulation, there is growing interest in understanding how MDSCs may influence the efficacy of vaccines, particularly in vulnerable populations. In this narrative review, we discuss whether MDSCs are able to regulate vaccine-induced immunity and whether their suppression can potentially enhance vaccine efficacy in vulnerable populations.</p>","PeriodicalId":14333,"journal":{"name":"International Reviews of Immunology","volume":" ","pages":"1-17"},"PeriodicalIF":4.3,"publicationDate":"2024-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142872024","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}

Due to the diversity of models employed, comparing results across different studies proves exceedingly challenging. The study conducted a search of pertinent PubMed articles from 2022 to April 15th, 2024. After relevant publications had been selected, the characteristics of each study were extracted, including animal strains, animal sex, sensitization methods, challenge methods, and reported outcome measures. The modeling parameters of Ovalbumin (OVA)-induced asthma model, and House Dust Mite-induced asthma model were analyzed. Additionally, we extracted data on the dose of OVA sensitization, alum administration, challenge OVA dose, and alum/sensitization OVA ratio from seven included studies. Subsequently, we conducted an analysis to determine the correlation between each of these factors and the lung resistance index (RI). This study presents an overview of the current mouse asthma models, offering valuable methodological guidance for researchers. Furthermore, this study highlights that certain parameters like sensitization dose, challenge dose, and so on, exert specific effects on the asthma lung resistance. However, there is a lack of standardized criteria and guidelines in this regard. The effects and underlying mechanisms of parameters on asthma responses remain unclear, necessitating further investigation into model parameters.</p>","PeriodicalId":14333,"journal":{"name":"International Reviews of Immunology","volume":" ","pages":"1-14"},"PeriodicalIF":4.3,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142800798","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}

Therefore, a deep knowledge of the intricate interplay between the tumor and the immune system is necessary. In the pursuit of combating breast cancer, the awakening of antitumor immunity has been proposed as a compelling avenue. Tumor stroma in breast cancers contains multiple stromal and immune cells that impact the resistance to therapy and also the expansion of malignant cells. Activating or repressing these stromal and immune cells, as well as their secretions can be proposed for exhausting resistance mechanisms and repressing tumor growth. NK cells and T lymphocytes are the prominent components of breast tumor immunity that can be triggered by adjuvants for eradicating malignant cells. However, stromal cells like endothelial and fibroblast cells, as well as some immune suppressive cells, consisting of premature myeloid cells, and some subsets of macrophages and CD4+ T lymphocytes, can dampen antitumor immunity in favor of breast tumor growth and therapy resistance. This review article aims to research the prospect of harnessing the power of drugs, adjuvants, and nanoparticles in awakening the immune reactions against breast malignant cells. By investigating the immunomodulatory properties of pharmacological agents and the synergistic effects of adjuvants, this review seeks to uncover the mechanisms through which antitumor immunity can be triggered.
