The dynamics of the ecological balance between the species might shift when invasive species are introduced to an environment.
<h3>
What is invasive species?</h3>
An organism that harms the ecology or the economy in a new habitat where it is not native is referred to as an invasive species.
Both the ecosystem's natural resources and human usage of those resources may be harmed by invasive species. The ballast water of oceangoing ships, purposeful and unintentional releases of aquaculture species, aquarium specimens or bait, and other methods can all be used to introduce an invasive species to a new area.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats. Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.

In rheumatoid Arthritis patients, NK cell levels were abnormally elevated, possibly due to high serum levels of IL-2.
Rheumatoid arthritis (RA), is an autoimmune disease that means our own immune system attacks self healthy cells in the body by mistake, causing inflammation (painful swelling),mainly attacks the joints.
The given study is to investigate the relationship between serum interleukin-2 (IL-2) levels and disease activity.
This study also showed the relationship between absolute numbers of peripheral lymphocyte subsets, autoantibodies, and associated cytokines in patients with rheumatoid arthritis (RA).
The results showed that the number and percentage of NK cells were positively correlated with serum IL-2 levels so, IL-2 can be a reason for elevated level of NK cells
