Reticular connective tissue Reticular connective tissue Reticular connective tissue is a type of connective tissue with a network of reticular fibers, made of type III collagen ("reticulum" = net or network). Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. Reticular fibers are synthesized by special fibroblasts called reticular cells. The fibers are thin branching structures. Reticular connective tissue is found around the kidney, the spleen, and lymph nodes, Peyer's patches as well as in bone marrow. The fibers form a soft skeleton (stroma) to support the lymphoid organs (lymph node stromal cells, red bone
Omega-6 fatty acid to diverse receptors found in every tissue of the body. Linoleic acid (18:2, "n"−6), the shortest-chained omega-6 fatty acid, is one of many essential fatty acids and is categorized as an essential fatty acid because the human body cannot synthesize it. Mammalian cells lack the enzyme omega-3 desaturase and therefore cannot convert omega-6 fatty acids to omega-3 fatty acids. Closely related omega-3 and omega-6 fatty acids act as competing substrates for the same enzymes. This outlines the importance of the proportion of omega-3 to omega-6 fatty acids in a diet. Omega-6 fatty acids are precursors to endocannabinoids, lipoxins, and specific
