Background

CD21 (CR2) and CD35 (CR1) are key complement receptors predominantly expressed on B cells and follicular dendritic cells (FDCs). CD21, also known as the C3d receptor, binds to complement fragments like C3d and iC3b, playing a crucial role in B cell activation and regulation of immune responses. It also serves as the receptor for Epstein-Barr virus (EBV) on B cells. CD35, on the other hand, binds to C3b and C4b, facilitating phagocytosis and immune complex clearance. It helps in the activation of B cells and regulation of complement activity. Both receptors are involved in antigen presentation and immune complex internalization, contributing to both innate and adaptive immune responses.

Tough ball. Perfect for large chewing breeds.
Color: 3 Colors
My German Shepherd Dog is a year and half old, and she loves these. They truly are pretty indestructible. It took her a little bit to figure out how to squeak it bc they are tough, but now it’s easy for her. They bounce well too. They are larger than a normal tennis ball but a good size for a large dog. Luna is 85 lbs. I would purchase they again, but I probably won’t need to for awhile.

Enjoyable For Our Dogs
Color: 3 Colors
Very durable material. They have a little squish too them for easy pick up for our 50 pound dogs. Our dogs love all balls. They have a little weight to them, but not excessive for a medium to large size dog. We have an English Springer Spaniel and a Goldendoodle. Fun for playtime, but you probably won’t want to throw them around the house.

A little too hard for our dog.
Color: 4 Colors
These are definitely durable balls. They are a harder than our dog prefers. He does play with them a little and enjoys squeaking them, but he doesn't like to play fetch with them and that is primarily the only thing he really enjoys doing with balls.
