Background

Interferon lambda 3 (IFN-λ3), also known as interleukin-28B (IL-28B), is a type III interferon that plays a crucial role in the innate immune response against viral infections. IFN-λ3 is produced in response to viral stimuli and exerts potent antiviral effects by inducing the expression of interferon-stimulated genes (ISGs) that inhibit viral replication and spread. Similar to other type III interferons, IFN-λ3 signals through the IFN-λ receptor complex, which consists of IL-10R2 and IL-28Rα subunits, leading to the activation of downstream signaling pathways involved in antiviral defense. IFN-λ3 has been implicated in the immune response to various viral infections, including hepatitis C virus (HCV) and influenza virus, and is considered a promising therapeutic target for the treatment of viral diseases.

Looks nice, but rusted after 6 months of use
Color: Black
The caddy was aesthetically pleasing, with enough room to hold my dish soap, hand-soap and sponge as well as a brush. I really love how it looks, but only after 6 months of using this, the wires in the holder is already rusted. It looks nice but not really of good quality.

Works as expected

It does exactly what it is supposed to do. No water collection on the sink and hold several of my kitchen cleaning items. It holds 3 sink stoppers a sponge and a scrubbers and a soap dispenser.
