Background

CD40 is also known as TNFRSF5, Bp50, CDW40, MGC9013, TNFRSF5 and p50, is a member of the TNF receptor superfamily which are single transmembrane-spanning glycoproteins, and plays an essential role in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. CD40 is a costimulatory protein found on antigen presenting cells and is required for their activation. The binding of CD154 (CD40L) on TH cells to CD40 activates antigen presenting cells and induces a variety of downstream effects. CD40 contains 4 cysteine-rich repeats in the extracellular domain, and is expressed in B cells, dendritic cells, macrophages, endothelial cells, and several tumor cell lines. Interaction of CD40 with its ligand, CD40L, leads to aggregation of CD40 molecules, which in turn interact with cytoplasmic components to initiate signaling pathways. Early studies on the CD40-CD40L system revealed its role in humoral immunity. Both CD40 and CD40 L have a membrane form and a soluble form generated by proteolytic cleavage or alternative splicing. CD40 and CD40L are widely expressed in various types of cells, among which B cells and myeloid cells constitutively express high levels of CD40, and T cells and platelets express high levels of CD40L upon activation. CD40L self-assembles into functional trimers which induces CD40 trimerization and downstream signaling. CD40/CD40L immune checkpoint leads to activation of both innate and adaptive immune cells via two-way signaling. CD40/CD40L interaction also participates in regulating thrombosis, tissue inflammation, hematopoiesis and tumor cell fate. The mechanisms of benefits include immune cell activation and tumor cell lysis/apoptosis in malignancies, or immune cell inactivation in autoimmune diseases and allograft rejection.

Great for using behind me on Zoom calls
Color: Black, Size: 1 Large Panel
This works great as a place to put tapestries behind me when I'm on Zoom calls... much nicer than blurring out the background. Easy to put together, large, works great.

Good quality, very adorable solution.
Color: Black, Size: 1 Large Panel
Easy to put together and take apart. Wish it had a storage bag of some sort—that would be very helpful. Used it for our mom while she was on hospice at home. The wheels made it very easy to move around as necessary. Nice and tall and wide for privacy. Highly recommend.

Nice, large room divider for privacy
Color: Black, Size: 1 Large Panel
Easy to assemble. Fabric screen covers the large frame very well and provides privacy by separating spaces. I would not exactly call it sturdy, but it does the job and stands freely with no problem. It’s lightweight and portable if you need to move it. Came with a screwdriver and wrench tool for assembly.

Perfect solution
Color: Black, Size: 2 Large Panels, Color: Black, Size: 2 Large Panels
Was a perfect solution to blocking off a part of a room for guest stay. My only wish was a bag for it to go in while not in use. Right now we’ve got it tucked away in a corner where it’s waiting to be used again. I put one wheel through a wooden partition gate (for dogs) and pushed a couch up against it and it held great keeping young kids out of the room. Though the dog figured it out pretty quickly haha I love the fabric in between the sections as well as the fact that they can be completely separate for individual use as needed. Makes it very useful in more scenarios.
