Why is it called Barcelona chair?
The Barcelona chair is a chair designed by Ludwig Mies van der Rohe and Lilly Reich, for the German Pavilion at the International Exposition of 1929, hosted by Barcelona, Catalonia, Spain. The chair was first used in Villa Tugendhat, a private residence, designed by Mies in Brno (Czech Republic).
Why is Barcelona Chair expensive?
In the traditional design houses the cost of a Barcelona Chair is the cost of the original design and that includes the license of the original brand. That increases sharply its cost.

A decrease in the CD4/CD8 ratio in Hashimoto’s thyroiditis hypothyroid patients was observed, in contrast to an increase in the ratio in autoimmune hyperthyroid patients. This points to the CD4/CD8 ratio as a differential characteristic between the two autoimmune (hypothyroid and hyperthyroid) entities, independent of free thyroxine levels.

The CD4/CD8 ratio is a reflection of immune system health. CD4 cells (also known as CD4 lymphocytes or T-helper cells) help coordinate the immune response by stimulating other immune cells, such as macrophages, B lymphocytes (B cells), and CD8 cells to fight infection. Untreated HIV targets and destroys CD4 cells.

The CD4:CD8 ratio is rarely measured below 1.0 in healthy subjects (Amadori et al., 1995), so an inverted CD4:CD8 ratio is often viewed as clinically relevant (Zaman et al., 2000; Pahwa et al., 2008).
