Special Issue Information

Dear Colleagues, 

The forthcoming Special Issue on Host–Pathogen Interactions and Pathogenesis is poised to be a ground-breaking compilation of cutting-edge research situated at the nexus of microbiology, immunology, and disease pathogenesis. Its primary objective is to unravel the intricate dynamics governing the relationships between hosts and pathogens, shedding light on the underlying mechanisms driving infection and disease progression.

We are pleased to invite you to this special issue which aims to contribute to a comprehensive overview of the current state of research in the dynamic field of host–pathogen interactions. By synthesizing diverse perspectives and featuring ground-breaking studies, the issue aims to contribute significantly to our understanding of infectious diseases. Moreover, it seeks to pave the way for future advancements in the prevention and treatment of infectious diseases by fostering collaboration and knowledge exchange among researchers.

The special aims to include following themes (but not limited to) for Submissions:

  1. Molecular Insights into Interactions: This theme invites studies delving into the molecular intricacies of host–pathogen interactions, exploring the strategies employed by pathogens to exploit host cellular machinery and the intricate defense mechanisms mounted by hosts.
  2. Emerging Pathogens and Global Health: Researchers are encouraged to spotlight research on emerging pathogens and their global health impact, addressing challenges posed by these agents and proposing strategies for surveillance, prevention, and control.
  3. Immunomodulation and Pathogenesis: A central theme exploring the immunomodulatory tactics employed by pathogens to establish and sustain infection, offering valuable insights for the development of targeted therapeutic interventions.
  4. Technological Advances and Methodological Innovations: This theme showcases the latest technological and methodological innovations, from advanced imaging techniques to high-throughput omics approaches, expanding our understanding of pathogenesis.

In this Special Issue, original research articles and reviews are welcome.

Mycobacterium tuberculosis (Mtb) ranks as the most lethal human pathogen, able to fend off repeated attacks by the immune system or medications. PE_PGRS proteins are hallmarks of the pathogenicity of Mtb and contribute to its antigenic diversity, virulence, and persistence during infection. M. smegmatis is a nonpathogenic mycobacterium that naturally lacks PE_PGRS and is used as a model to express Mtb proteins. PE_PGRS has the capability to evade host immune responses and enhance the intracellular survival of M. smegmatis. Despite the intense investigations into PE_PGRS proteins, their role in tuberculosis remains elusive. We engineered the recombinant M. smegmatis strain Ms-PE_PGRS38. The result shows that PE_PGRS38 is expressed in the cell wall of M. smegmatis. PE_PGRS38 contributes to biofilm formation, confers permeability to the cell wall, and shows variable responses to exogenous stresses. PE_PGRS38 downregulated TLR4/NF-κB signaling in RAW264.7 macrophages and lung tissues of infected mice. In addition, PE_PGRS38 decreased NLRP3-dependent IL-1β release and limited pathogen-mediated inflammasome activity during infection. Moreover, PE_PGRS38 inhibited the apoptosis of RAW264.7 cells by downregulating the expression of apoptotic markers including Bax, cytochrome c, caspase-3, and caspase-9. In a nutshell, our findings demonstrate that PE_PGRS38 is a virulence factor for Mtb that enables recombinant M. smegmatis to survive by resisting and evading the host’s immune responses during infection.
