1. Motility of human polymorphonuclear leukocytes : An image processing approach
Abstract : Cell motility is essential for polymorphonuclear leukocyte (PMN) function in the defense against invading microorganisms and in inflammatory processes. Using digital video microscopy and image processing, individual cells were studied during random locomotion, chemotactic locomotion and phagocytosis. READ MORE

2. Transmigration of Toxoplasma gondii across biological barriers
Abstract : Toxoplasma gondii is an obligate intracellular parasite that can likely infect all warm-blooded vertebrates, with estimates of up to 30% of the global human population being infected. Although infection with T. gondii is usually asymptomatic or mild, in immunocompromised individuals infection can lead to lethal toxoplasmic encephalitis. READ MORE

3. Signaling determinants in Trojan horse-mediated dissemination of Toxoplasma gondii
Abstract : Toxoplasma gondii is an obligate intracellular parasite that infects all warm-blooded vertebrates including one third of the global human population. While infection is typically asymptomatic in healthy human hosts, reactivated and acute infection in immunosuppressed or immunecompromised individuals can lead to lethal toxoplasmic encephalitis After ingestion, the parasite crosses the intestinal epithelium and rapidly achieves systemic dissemination, ultimately establishing chronic infection in the brain.

4. Functions of integrin receptors in extravascular neutrophil migration and respiratory burst
Abstract : Leukocytes circulate in the vasculature, but, must leave the blood stream and migrate through the surrounding tissue to exert their protective functions in inflammation. Numerous studies have revealed that intravascular leukocyte-endothelial cell interactions involve functions of adhesion molecules belonging to the selectin and integrin receptor families. READ MORE

5. Interaction of human blood platelets, lymphocytes and monocytes with vascular laminin isoforms
Abstract : Inflammatory and immune responses play a fundamental role in both health and disease, and leukocytes are important actors in these processes. Migration of the leukocytes to sites of injury or inflammation is a crucial component of innate and adaptive immunity. It is currently accepted that leukocyte extravasation is a multistep process.
