Effect of Egyptian spitting cobra Naja nubiae crude venom on immunogenic activity of rats.

Snakes show defensive activities, often counting visual or auditory displays against an aggressor. The study observed what happens to rats administered subcutaneously sub-lethal doses of crude venom Naja nubiae. The pro-inflammatory cytokines, such as tumor necrosis alpha (TNF-α) and interleukin-6 (IL-6), as well as the anti-inflammatory cytokines such as interleukin-10 (IL-10), and inflammatory mediator's prostaglandin E-2 (PG-E2), were evaluated. Vascular permeability (VP) was employed to assess how leaky or permeable blood vessels are in various tissues and organs, including the rat peritoneal cavity and lymphoid organs. Lymphoid organs' histological alterations brought on by Nubiae venom. The study found that the two venom doses—1/4 and 1/2 LD 50 —induced high levels of inflammatory activity as evidenced by the production of inflammatory cytokines. These findings demonstrated that venom enhanced innate immunity through specifically increased T helper cells, IL-6, TNF-α, IL-10, and PG-E2. The results reveal whether the venom has an immunomodulatory effect and promotes inflammation. The data have a substantial impact on the development of new drugs and treatments for inflammatory conditions. [Display omitted] • Both crude venom doses of N. nubiae −1/4 and 1/2 LD50—induced the production of inflammatory cytokines. • N. nubiae crude venom enhanced innate immunity through specifically increased T helper cells, IL-6, TNF-α, IL-10, and PG-E2. • Lymphoid organs' histological alterations brought on by Nubiae venom. • Vascular permeability was employed to assess how permeable blood vessels are in the peritoneal cavity and lymphoid organs. • The study has a substantial impact on the development of new treatments for inflammatory conditions of N. nubiae venom.
