Significant QTL affecting six morphometric traits including length and depth, are reported.

There were no differences between the histological appearance of the testes of GnRHa-treated and control males, and almost all of them contained intra-testicular spermatozoa.

In addition, two GnRHa-implanted females in 2005 were found to be ovulated at the time of sacrifice, and their eggs were fertilized in vitro with sperm from spermiating males, which resulted in viable embryos and larvae.

Yet, after antigen engagement or immune complex (IC) deposition, FDCs lacking IKK2 fail to upregulate VCAM-1 and ICAM-1, and GCs remain sterile. These findings demonstrate that IKK2-independent function of p55TNFR on FDCs is sufficient to support the development of FDC networks and GCs, while FDC-specific IKK2 is indispensable for the generation of efficient humoral immune responses. |
