Pain in osteoarthritis poses a substantial social and economic burden with fewer than 25% of patients having adequate pain control. NGF has emerged as a key driver of pain behavior in murine studies and antibodies to NGF are potent analgesics in human osteoarthritis. Using a novel virus-like particle, von Loga et al created a therapeutic vaccine that reversibly induced antibodies against NGF and abrogated pain behavior in murine osteoarthritis.

Sesquizygosis -- whereby twins are genetically identical to each other with respect to one parent but differ from each other by approximately 50% with respect to the composition of DNA inherited from the other parent -- is a third form of twinning. Genetically, sesquizygosis can be considered to be on a continuum between monozygosis and dizygosis. It probably arises after heterogoneic assortment of two paternal genomes and one maternal genome during the first postzygotic cleavage division.
