The immune system protects from infections primarily by detecting and eliminating invading pathogens. This is predominantly mediated by innate immune cells like neutrophils, monocytes and dendritic cells (DCs) expressing specific receptors recognizing pathogen-associated molecular patterns. DC activation by pathogens leads to the initiation of antigen-specific adaptive immune responses, thereby bridging the innate and adaptive immune systems. However, various pathogens have evolved immune evasion strategies to ensure their survival. In this review, we highlight recent findings on how various microorganisms or their structural features affect or modulate DC development and whether this has any consequences for a protective immune response.

The thrombolytic protease tissue plasminogen activator (tPA) is expressed in the CNS, where it regulates diverse functions including neuronal plasticity, neuroinflammation, and blood-brain-barrier integrity. However, its role in different brain regions such as the substantia nigra (SN) is largely unexplored. In this study, we characterize tPA expression, activity, and localization in the SN using a combination of retrograde tracing and β-galactosidase tPA reporter mice.

Background: Sepsis and shock are common complications of necrotising soft tissue infections (NSTI). Sepsis encompasses different endotypes that are associated with specific immune responses. Hyperbaric oxygen (HBO) treatment activates the cells oxygen sensing mechanisms that are interlinked with inflammatory pathways.

Developing effective nanoplatforms for chemo-immunotherapy to achieve enhanced tumor suppression and systemic antitumor immunity has recently received extensive attention. Herein, we formulated a multifunctional DNA sandwich nanodevice, DSWAC/siPD-L1, based on triangular DNA origami, to implement enhanced cancer chemo-immunotherapy. Taking advantage of the tumor-targeting ability of the AS1411 aptamer, DSWAC/siPD-L1 efficiently delivered doxorubicin (DOX), CpG, and siPD-L1 into tumor cells.

The bioaccumulation and toxic effects of synthetic phenolic antioxidants (SPAs) in aquatic ecosystems are of growing concern due to their widespread use and potential environmental persistence. This study investigated the detoxification and toxicological impacts of 2,6-ditert-butyl-4-methylphenol (BHT), a representative SPAs, on clams Ruditapes philippinarum using environmentally relevant exposure concentrations. BHT bioaccumulation was observed in both gills and digestive glands, with higher levels in the latter.

In healthy individuals, cytomegalovirus (CMV) seropositivity is associated with impaired adaptive immune systems. We assessed whether the adverse effects of donor risk factors are influenced by the donor CMV serostatus.
