Oligosaccharides are basically carbohydrates formed by the union of three to six units of simple sugars or monosaccharides. However, in rare cases, as many as ten units of sugars have been seen to form an Oligosaccharide. They are either formed by combining molecules of monosaccharides or are formed from the breaking of complex sugars called polysaccharides. Very few oligosaccharides are found in nature from plants. To mention a few; Raffinose is formed of 3 molecules of monosaccharides, melibiose, gentianose and fructose. One oligosaccharide is obtained from arthropod’s blood and in a few plants which are Maltotriose which consists of three molecules of glucose. The molecular formula of Oligosaccharide is C37H62N2O29. It has a calorific va;ue of 1.5-2 cal/gm and is usually found in legumes, garlic, pear, watermelon and white onion. Many fruits also contain fructo-oligosaccharide.

Natural Killer (NK) cells play a critical role in the innate immune surveillance against cancer and viral infections. They are the "first responders" capable of spontaneously recognizing abnormal cells in the body, swiftly eliminating them through targeted cytotoxic mechanisms, and effectively producing pro-inflammatory cytokines and chemokines to recruit and activate other immune cells to initiate adaptive responses. Therefore, understanding the mechanisms of NK cell activation and identifying methods to stimulate their activation are crucial for the development of anti-tumor and antiviral drugs.
Mechanisms of NK Cell Activation NK cells are regulated by a dynamic balance between a series of activating and inhibitory receptors. Normal cells express major histocompatibility complex class…
