Permeabilization of the outer mitochondrial membrane initiates apoptotic cell death. B-cell lymphoma 2 (BCL-2) antagonist killer (BAK) and BCL-2-associated X (BAX) mediate mitochondrial poration, but how this process unfolds remains poorly defined. Two studies in this issue investigate the transition of dormant, inactive BAK monomer to a highly dynamic membrane-associated, pore-forming oligomer.

Chickens are renowned as a model for embryogenesis but have also been responsible for crucial advances in virology, cancer research and immunology. However, chickens are best known as a major source of animal protein for human nutrition, with roughly 80 billion chickens alive each year supplying meat and eggs, the vast majority part of a global poultry industry. As a result, avian immunology been studied intensively for over 60 years, and it has become clear that a major genetic locus in chickens determining resistance to infectious disease and response to vaccines is the major histocompatibility complex (MHC).

Co-expression gene module analysis in response to attenuated cercaria vaccine reveals a critical role for NK cells in protection against Schistosoma mansoni.

Background: Despite decades of research, an effective schistosomiasis vaccine remains elusive. The radiation-attenuated (RA) cercarial vaccine remains the best model for eliciting high levels of protection. We have recently explored this model in mice to identify potentially protective pathways by examining gene expression patterns in peripheral blood mononuclear cells (PBMC).

Distinct metabolites affect the phloem fungal communities in ash trees (Fraxinus spp.) native and nonnative to the highly invasive emerald ash borer (AGRILUS PLANIPENNIS).

Article Synopsis
  • Emerald ash borer (EAB) is an invasive pest severely affecting ash trees in North America and Europe, with native ash species showing resistance due to unknown mechanisms.
  • A study compared the phloem mycobiomes and metabolites of native and nonnative ash species, finding significant differences in mycobiome communities but no impact from EAB infestation.
  • The research highlights a complex relationship between tree chemistry and mycobiomes, suggesting that the co-evolution of native trees and EAB plays a role in their interactions.

The merozoite surface protein 1 (MSP1) is the most abundant protein on the surface of the invasive merozoite stages of and has long been considered a key target of protective immunity. We used samples from a single controlled human malaria challenge study to test whether the full-length version of MSP1 (MSP1) induced antibodies that mediated Fc-IgG functional activity in five independent assays. We found that anti-MSP1 antibodies induced complement fixation via C1q, monocyte-mediated phagocytosis, neutrophil respiratory burst, and natural killer cell degranulation as well as IFNγ production.

The bug-killer fly (L.) (Diptera: Tachinidae) forms the respiratory funnel independently of the host's immune response.

In internal parasitism, the respiration strategy within the host's body is as essential as evading attack from the host's immune system. Tachinid flies are parasitoids of terrestrial arthropods, mostly insects, during their larval stage. To obtain oxygen while living in the host body, they build a cylindrical structure known as the respiratory funnel at the aperture opened by the tachinid larva on the host integument or trachea.
