Background

CD161 (encoded by KLRB1) is a C-type lectin-like type II transmembrane protein expressed on natural killer (NK) cells and subsets of T cells, where it functions as an inhibitory receptor on NK cells to suppress cytotoxicity and cytokine secretion, while on T cells it acts as a costimulatory receptor that enhances responsiveness to T-cell receptor (TCR) stimulation by interacting with its ligand LLT1 and is associated with improved survival in various cancers due to its role in amplifying TCR signaling and promoting rapid effector functions.

Too big
Color: Pink, Size: Medium
Seems like good quality, the sizes run big, I normally wear medium in most clothes, but the small is still too big for me

low-maintenance shirt that fits perfectly
Color: Black, Size: 3X-Large
This COOFANDY Casual Button Down is a fantastic addition to a summer wardrobe, offering both great fit and high quality. The material is impressively wrinkle-free, which keeps it looking sharp and crisp even after a full day of wear. It is specifically designed to be worn untucked, and the length is just right—offering a modern, relaxed silhouette that doesn't look sloppy. The fabric feels durable yet breathable, making it comfortable for both casual outings and slightly dressier occasions. If you’re looking for a low-maintenance shirt that fits perfectly right out of the wash, this is an excellent choice.

My husband loves these shirts
Color: Dark Blue, Size: Large
My husband just loves these shirts. He has one in every color, I think. Great quality, good price, breathable, true to color, and super comfy. Nice enough to wear to a nice dinner but can be dressed down w a pair of shorts and flip flops. By far the best find I have found!
