Adaptive Immunity in Marsupials. [PDF]
J Exp Zool A Ecol Integr PhysiolComparison of the marsupial and eutherian adaptive immune systems. ABSTRACT Marsupials diverged from eutherian mammals 125–160 million years ago. Although evolutionarily distinct, both groups of mammals can produce complex adaptive immune responses to antigens with several key differences.

Anatomical description of the jaw muscles and theoretical bite force assessment in South American opossums using manual and digital dissection methods. [PDF]
J AnatManual and virtual dissections were employed to examine the masticatory muscle architecture and bite force of three South American marsupials. The organisation of the muscles differed between species, with predicted bite forces exceeding previous estimates.

Trichromacy in Australian Marsupials [PDF]
Current Biology, 2002 Vertebrate color vision is best developed in fish, reptiles, and birds with four distinct cone receptor visual pigments. These pigments, providing sensitivity from ultraviolet to infrared light, are thought to have been present in ancestral vertebrates.

Litter size and reproductive condition of small mammals in southern Goiás, Brazil
Mammalogy Notes, 2021 Litter size and reproductive conditions are important in natural history. However, this information is scarce in scientific literature. Here, we presented litter size data for eight small mammal species (four marsupials and four rodents) and investigated

Morphological study of larynx, trachea, and lungs of Didelphis marsupialis (LINNAEUS, 1758) [PDF]
Veterinary World, 2020 Background and Aim: From a biomedical point of view, the value of marsupials as a model of primitive mammals is indisputable. Among its species, the possum is a model that allows the study of the ontogeny of different organic systems, as well as their ...

Journal of General Virology, 1979 A virus-like particle was observed in two continuous cell lines derived from the marsupial Sminthopsis crassicaudata (Fat-tailed Dunnart). The development of the particle was similar to the development of D-type oncoviruses. Initially, a crescentof nucleoid material was observed near the nucleus in the region of the Golgi apparatus.

Mechanisms of Choice in X-Chromosome Inactivation
Cells, 2022 Early in development, placental and marsupial mammals harbouring at least two X chromosomes per nucleus are faced with a choice that affects the rest of their lives: which of those X chromosomes to transcriptionally inactivate.
