Phosphatidylserine is a global immunosuppressive signal in efferocytosis, infectious disease, and cancer [PDF]
Apoptosis is an evolutionarily conserved and tightly regulated cell death modality. It serves important roles in physiology by sculpting complex tissues during embryogenesis and by removing effete cells that have reached advanced age or whose genomes ...

Effects of Actinomycin D and Ultraviolet and Ionizing Radiation on Pichinde Virus [PDF]
Actinomycin D (0.05 μg/ml) suppresses the synthesis of ribosomal RNA of baby hamster kidney (BHK21) cells. The production of infectious Pichinde virus was enhanced in the presence of actinomycin D, although the production of virus particles was not substantially different from cultures inoculated in the absence of the drug.

Leishmania amazonensis parasites cause progressive disease in most inbred mouse strains and are associated with the development of diffuse cutaneous leishmaniasis in humans. The poor activation of an effective cellular response is correlated with the ability of these parasites to infect mononuclear phagocytic cells without triggering their activation ...

Antiviral activity of ribosome-inactivating proteins [PDF]
Producción CientíficaRibosome-inactivating proteins (RIPs) are rRNA N-glycosylases from plants (EC 3.2.2.22) that inactivate ribosomes thus inhibiting protein synthesis.

Synthesis of virus-specific polypeptides and genomic RNA during the replicative cycle of Pichinde virus [PDF]
A stock of plaque-purified Pichinde virus, prepared under conditions designed to limit the amounts of defective interfering virus, was used to infect BHK cells. At daily intervals after infection, cells were examined for infectious and radiolabeled virus particle production and for the synthesis of virus-specific polypeptides.

Several arenaviruses cause hemorrhagic fever disease in humans and pose a significant public health concern in their endemic regions. On the other hand, the prototypic arenavirus LCMV is a superb workhorse for the investigation of virus‐host interactions and associated disease.

Reassortant Analysis of Guinea Pig Virulence of Pichinde Virus Variants
The new world arenavirus Pichinde (PIC) is the basis of an accepted small animal model for human Lassa fever. PIC (Munchique strain) variant P2 is attenuated in guinea pigs, whereas variant P18 is extremely virulent. Previous sequence analysis of the S segments of these two viruses indicated a small number of possible virulence markers in the ...

Role of natural killer cells in Pichinde virus infection of Syrian hamsters [PDF]
Pichinde virus produced a fatal infection in adult MHA hamsters but not LSH hamsters after intraperitoneal inoculation. After footpad inoculation, an 8-day swelling response was observed in LSH but not MHA hamsters; however, both strains survived infection by this route.

Comparative Pathogenesis and Systems Biology for Biodefense Virus Vaccine Development
Developing vaccines to biothreat agents presents a number of challenges for discovery, preclinical development, and licensure. The need for high containment to work with live agents limits the amount and types of research that can be done using complete pathogens, and small markets reduce potential returns for industry. However, a number of tools, from

mTOR Regulation of Lymphoid Cells in Immunity to Pathogens [PDF]
Immunity to pathogens exists as a fine balance between promoting activation and expansion of effector cells, while simultaneously limiting normal and aberrant responses. These seemingly opposing functions are kept in check by immune regulators.
