cyst Scientific  
/ sĭst /
  1. An abnormal membranous sac in the body, containing a gaseous, liquid, or semisolid substance.

  2. A small, capsulelike form of certain organisms that develops in response to adverse or extreme conditions. Under adverse conditions, for instance, dinoflagellates form nonmotile resting cysts that fall to the ocean or lake bottom and can remain there for years before reviving. Certain invertebrates, such as the water bear (phylum Tardigrada), also develop cysts.


cyst Cultural  
  1. An abnormal saclike structure that develops in the body and is filled with fluid or semisolid material.

For many years, scientists assumed that each cyst housed a single, uniform type of parasite that remained inactive until it reawakened.

From Science Daily

Their research shows that every cyst contains multiple parasite subtypes, each performing different biological functions.

From Science Daily

"We found the cyst is not just a quiet hiding place -- it's an active hub with different parasite types geared toward survival, spread, or reactivation," said Emma Wilson, a professor of biomedical sciences in the UCR School of Medicine and lead author of the study.

From Science Daily

Each cyst is surrounded by a protective wall and packed with hundreds of slow-growing parasites known as bradyzoites.

From Science Daily

"Our research challenges that model. By applying single-cell RNA sequencing to parasites isolated directly from cysts in vivo, we found unexpected complexity within the cyst itself. Rather than a uniform population, cysts contain at least five distinct subtypes of bradyzoites. Although all are classified as bradyzoites, they are functionally different, with specific subsets primed for reactivation and disease."
