Chemotaxis: role in egg-sperm interaction and its evaluation
Abstract: Communication between spermatozoa and egg before contact by chemotaxis is prevalent throughout the animal kingdom. In most animal species, the prospects of the spermatozoa coming in contact with eggs are very slim in the absence of some guidance mechanism usually chemical in nature that has been acquired gradually. Such chemical guidance, sperm chemotaxis, is now recognized in many marine invertebrates, fish, amphibians, and a few mammals including humans. This suggests …

Infant’s Immunity w.s.r. to Compliment System: A General Review
Abstract: Infant’s mortality and morbidity rate in developing countries are at higher incidence due to infections. Various factors are responsible for infections, such as low socio-economic status, poor hospital facilities and malnutrition etc. The low level of compliment components and serum immunoglobulin in infants has been claimed to be the reason of defective opsonic activity in infants as well as defective generation of chemotaxis activity. Thus immune system during neonatal as …

Role of Human Neutrophils in Inflammation and its Modulation by Ixora coccinea
Abstract: Neutrophils are one of the key cells that actively participate in the innate immune reactions. Sequences of event of pathogen elimination by neutrophils are initiated with the activation of resting neutrophils. Pathogen is then eliminated by oxygen-dependent killing mechanism or oxygen-independent killing mechanism. This process includes margination, diapedesis, chemotaxis, phagocytosis and degranulation of neutrophils. Although, these mechanisms of the neutrophils are targeted to eliminate the pathogens and protect the body, …
