Summary: This study examines the interaction between neutrophils and macrophages during JP2 Aggregatibacter actinomycetemcomitance infection and factors involved in inflammatory resolution and efferocytosis. Neutrophil efferocytosis potentially reduces during JP2 infection, promoting JP2 clearance and contributing to tissue damage. Macrophages play a role in regulating neutrophil clearance and polarization during JP2 infection.

Summary: Periodontitis is an inflammatory disease characterized by the destruction of periodontal tissues, and its onset is influenced by systemic factors. The destruction of periodontal tissues is believed to be a result of unresolved inflammation. Efferocytosis, the clearance of dying cells, plays a critical role in inflammation resolution, and defective efferocytosis contributes to the persistence of chronic inflammatory diseases. This review explores the role of macrophage efferocytosis in the pathogenesis of periodontitis and highlights emerging therapeutic strategies for future periodontal treatments.

Summary: Novel pentafluorobenzenesulfonamide derivatives with different molecular scaffolds were synthesized and evaluated for antitumor activities against multiple cancer cell lines. Dihydroimidazoline-containing analogues and their Diels-Alder cycloadducts showed enhanced cytotoxicity, while incorporation of other heterocyclic cores via nucleophilic substitution resulted in decreased potency. Selected analogues were found to induce apoptosis in cancer cells through caspase-dependent processes.

Summary: This study found that pre-incubation of macrophages with apoptotic cells and subsequent challenge with Encephalitozoon cuniculi microsporidia increased phagocytosis and promoted pathogen multiplication. Additionally, efferocytosis of apoptotic cells and pathogen challenge decreased macrophage viability and led to the polarization of macrophages to an M2 profile, facilitating pathogen development.

Summary: In this study, a series of novel derivatives of betulinic acid (BA) and oleanolic acid (OA) were synthesized and evaluated for their anticancer properties. The results showed that two derivatives of OA exhibited the strongest antitumor activity against three human cancer cell lines. Further experiments revealed that these derivatives induced apoptosis in the cells through activation of the intrinsic apoptotic pathways mediated by reactive oxygen species (ROS) and caspase-3 signaling.

Summary: Efferocytosis is crucial for maintaining tissue homeostasis and involves activation of transcription factors such as PPAR and LXR. This study explored the transcriptional profile of macrophages following uptake of apoptotic cells, showing upregulation of PPAR and LXR pathways. The activation mechanisms of PPAR and LXR in efferocytotic human macrophages were elucidated, providing insights into their roles in metabolic and inflammatory responses.

Summary: This study investigated the effects of BHB on neutrophil apoptosis and the underlying regulatory mechanisms during ketosis. The results showed that high concentrations of BHB inhibit apoptosis in bovine neutrophils by activating the ERK1/2 and AKT signaling pathways. These findings have important implications for understanding systemic inflammation in ketotic cows.

Summary: This study found that ZBP1 induced during coronavirus infection limits the efficacy of IFN therapy by driving inflammatory cell death and lethality. Inhibiting ZBP1 activity may improve the efficacy of IFN therapy for COVID-19 and other infections and inflammatory conditions where IFN-mediated cell death and pathology occur.

Summary: Multiple lines of evidence support the value of moderate fever in host survival, but the mechanisms involved are still unclear. By using a cold-blooded fish model, researchers were able to study the natural kinetics of fever induction and regulation, as well as a wide range of tolerated temperatures. The results showed that fever activates specific immune mechanisms, improves pathogen clearance, inhibits inflammation, and enhances wound repair. Artificial hyperthermia, commonly used as a fever model, partially replicates the benefits of natural fever. Overall, this study defines fever as an integrative host response that regulates acute inflammation, and demonstrates its importance in the evolution of organisms.
