Abstract:
Thelaziasis is an ocular arthropod-borne, zoonotic disease of the eye infecting the conjunctival sac, lacrimal duct, and lacrimal gland caused by a nematode of the genus Thelazia. We report the first case of human ocular thelaziasis in Nepal in a 6-month-old child from a Rukum district, Nepal. The infant presented with conjunctivitis, and his visual acuity and dilated fundal examination were normal. A total of 6 worms were removed for identification. Collected nematodes were identified based on morphological keys as Thelazia callipaeda. The patient's symptoms improved after removal of the nematodes.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
