Neurogenesis

Neurogenesis is the mechanism whereby neurons are developed within the nervous system. It involves the formation of highly specialized neurons within the brain, both in fetal and adult growth.

Cytokine Regulation

The body’s defence against harmful stimuli or antigens depends on its recognition of those antigens. Recognition is followed by activation of the innate and adaptive immune responses.

Diffusion and Red Blood Cells

Animals breathe in oxygen, following which it must be delivered to all the organs in the body. This process involves red blood cells and diffusion.

How are Exosomes Isolated?

Exosomes can be isolated from cells using typical methods for purifying cell fractions. The challenge in isolating vesicles is differentiating them from other types of membrane material in the cell culture supernatant.

Microtubule Motor Proteins

Microtubule motor proteins move across the microtubule, transporting cellular cargo within the cell. They are responsible for mitosis, cellular transport and the movement of organelles.

The Mechanism of DNA Damage by UV Radiation

Solar ultraviolet radiation (UV) exposure triggers DNA damage, a preliminary step in the process of carcinogenesis. Exposure to UV radiation alters the structure of DNA, affecting the physiological processes of all living systems ranging from bacteria to humans.
