Arunachal macaque It is the first species of macaque to have been discovered since 1903, when the Indonesian Pagai Island macaque was discovered. This monkey was reported on the basis of a good quality photograph as the holotype. In 2011, some researchers suggested, on the basis of morphological variation within the Assamese macaque, that it might be better treated as a subspecies. Subsequently, it was also discovered in Bhutan, where it was observed and photographed in the Trashi Yangshi area in 2006. The Arunachal macaque is compactly built and has a very dark face. It lives at high altitudes, between 2000 m
Rhesus macaque Michael Katze of University of Washington, Seattle, infected macaques with 1918 and modern influenzas. The DNA microarray showed the macaque genomic response to human influenza on a cellular level in each tissue. Both viruses stimulated innate immune system inflammation, but the 1918 flu stimulated stronger and more persistent inflammation, causing extensive tissue damage, and it did not stimulate the interferon-1 pathway. The DNA response showed a transition from innate to adaptive immune response over seven days. The full sequence and annotation of the macaque genome is available on the Ensembl genome browser.
