One critical innate immune cell type is the macrophage. Macrophages play key roles in pathogen clearance and tissue repair. Many pathogens secrete pore-forming toxins (PFTs), which macrophages must detect, then defend against them and respond to them. Similarly, macrophages also detect and respond to innate immune PFTs deployed against bacteria, and target cells, including perforin and the membrane, attack the complex of complement. Finally, macrophages themselves utilize PFTs like gasdermin D and mixed-lineage kinase-like (mlkl) to execute the cell death pathways of pyroptosis and necroptosis, respectively, to deny intracellular pathogens refuge. Interplay between macrophages and toxins occurs at many steps and leaves many unknowns in the field. Three broad outstanding questions in the field are: How do macrophages discriminate between PFTs to correctly promote or suppress inflammation? What molecular mechanisms drive macrophage responses to PFTs? How do bacteria and other pathogens hijack macrophage responses to PFTs to promote infection?
This Special Issue will focus on the interplay between macrophages and related myeloid cells with pore-forming toxins, including both the use of pore-forming toxins by these cells, and the response of these cells to toxins. This includes the biology behind cell death processes that require pore-forming toxins, macrophage responses to external toxins deployed against other bacteria and cells, and inflammation, immunosuppression, signaling, and other responses to pore-forming toxins.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a double-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Toxins is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
