Podocytes are specialized cells that play a crucial role in the filtration process of the kidneys. They are located in the glomerulus of the kidney and have finger-like projections called foot processes that wrap around the capillaries to form a filtration barrier. This barrier helps to prevent the loss of important proteins and blood cells while allowing waste products to be excreted in the urine. Research on podocytes focuses on understanding their structure, function, and how they are involved in various kidney diseases such as glomerulonephritis, diabetic nephropathy, and focal segmental glomerulosclerosis. This research aims to identify new therapeutic targets and develop treatments to protect and repair podocytes, ultimately improving kidney function and preventing the progression of kidney disease.
