Actin Microfilaments, Myosin and Muscle: Cytoskeletal Control of the Cortex and Cytoplasmic Membrane

Fingers of the cytoplasmic membrane can be rapidly projected by the cytoskeleton and just as rapidly contracted. The membrane is pushed out by the addition of protein subunits to rigid actin microfilaments. Motor proteins, such as myosin, can attach to different actin microfilaments and force … Continue reading Actin Microfilaments, Myosin and Muscle: Cytoskeletal Control of the Cortex and Cytoplasmic Membrane

Leishmania Parasite Life Cycle: Leishmaniasis is a Parasitic Disease Caused by a Protozoan

Leishmania parasites are a group of closely related parasites that are transmitted to humans by the bite of a sand fly. They are protozoa belonging to the taxonomic genus Leishmania—tiny single celled parasites that cause leishmaniasis. Leishmaniasis takes different forms: cutaneous, visceral, and mucocutaneous. The … Continue reading Leishmania Parasite Life Cycle: Leishmaniasis is a Parasitic Disease Caused by a Protozoan
