T cell cross-reactivity among viruses of the paramyxoviridae
Abstract:
Blastogenesis and delayed-type hypersensitivity assays were used to examine mouse T cell responses to five viruses representing the three genera of the Paramyxoviridae. Cross-reactive T cell responses were observed in a lympho-proliferative assay for measles, mumps, respiratory syncytial, canine distemper and parainfluenza type 3 virus. Confirmation of T cell cross-reactivity among measles, mumps and respiratory syncytial virus was obtained with a delayed-type hypersensitivity test. These results show that T cell cross-reactivity is common for Paramyxoviridae viruses, even though these viruses show virtually no inter-genus antibody cross-reactivity. The cross-reactivity among respiratory syncytial, measles and mumps virus at the T cell level may have implications for usage of the attenuated measles/mumps/rubella (MMR) vaccine. Respiratory syncytial virus is contacted by many children before they receive the MMR vaccine and T cells induced by respiratory syncytial virus may influence subsequent development of immunity to measles and/or mumps virus.

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
