| Some new data concerning virology, prions and immunology |
| Danger of re-emergence of influenza H2N2 pandemic? A RNA virus within the parasite Leishmania affects host’s immune response, leading to mucocutaneous leishmaniasis. Two distinct prion populations – infectious and toxic occur in two phases. Innate lymphoid cells play a role in intestinal postnatal defense before the gut is fully colonized by microbial symbionts. Fetal and adult mammalian T cells are distinct populations that arise from different populations of hematopietic stem cells; fetal T cell lineage is biased toward immune tolerance. A nanoparticle-based vaccine resembling a virus in size and composition, recapitulates the immunogenicity of live viral vaccines. Bovine neonatal pancytopenia (BNP) is an immune-mediated disease caused by colostrum-derived alloimmune antibodies directed against calf leukocytes. |
