Abstract Tight junctions (TJs) between adjacent Sertoli cells are believed to form immunological barriers that protect spermatogenic expressing autoantigens from autoimmune responses. However, there is no direct evidence cell TJs (SCTJs) do indeed barriers. Here, we analyzed male mice lacking claudin-11 ( Cldn11 ), which encodes a SCTJ component, and found autoantibodies against antigens of spermatocytes/spermatids in their sera. Defective spermatogenesis -deficient was not restored on...

A rearrangeable 128*128-channel optical switch based on a multistage network configuration is demonstrated. The properties of components required for achieving up to 1000*1000-channel switches are discussed, taking into account the diffraction limit and liquid crystal light modulator (LCLM) crosstalk. An examination insertion loss crosstalk reveals an average 7.9 -21.2 dB, respectively, worst-case 11.0 -12.8 respectively. Such low-loss low-crosstalk indicate that proposed structure suitable...
