Abstract
Interferon tau (IFN-τ) is a ruminant-specific type I IFN secreted by a conceptus before its attachment to the uterus. IFN-τ induces the expression of IFN-stimulated genes (ISGs) via the type I IFN receptor (IFNAR), which is
composed of IFNAR1 and IFNAR2 subunits in the endometrium. However, expression patterns of IFNARs during the estrous cycle have not been reported. We hypothesized that the response to a type I IFN changes along with IFNARs and the
IFN-regulatory factors (IRFs) driving transcription of IFN signal-related genes and modulating a type I IFN signal during the estrous cycle. We investigated the estrous cycle stage-dependent type I IFN induction of ISGs and
expression patterns of IFN signal-related genes in bovine endometrial tissues. Endometrial tissue pieces collected from bovine uteri at each estrous stage (early, mid, and late) were cultured with or without recombinant bovine
IFN-α or concentrated pregnant uterine flushing (PUF) on day 18 after confirming the presence of a conceptus. IFN-α and PUF each significantly increased the expression of ISGs in endometrial tissues. The induction levels of the
typical ISGs (MX1-a and ISG15) were significantly higher at the mid stage and correlated with high expression of IRFs at the mid stage. The immunostaining of IFNARs showed strong
fluorescence intensities in luminal and glandular epithelia at the early and mid stages. Collectively, these results suggest that the endometrium exhibits estrous cycle stage-dependent responsiveness to type I IFN that may be
associated with the expression of IFNARs and IRFs for pregnancy recognition.

Abstract
Bovine interferon (bIFN) τ plays a crucial role in maternal-fetal recognition
and was expressed using a Bombyx mori (Bm) nuclear polyhedrosis virus
(silkworm baculovirus) gene expression system. The biological effects of Bm-recombinant
bIFNτ (rbIFNτ) on prostaglandin (PG) F2α synthesis were investigated in
cultured bovine endometrial epithelial cells with oxytocin (OT, 100 nM) and on the
in vitro development of bovine embryos. Bm-rbIFNτ and OT were shown to
suppress PGF2α production in a dose-dependent manner. When in
vitro produced morula stage embryos were cultured for 72 hr in modified CR1aa
medium supplemented with or without rbIFNτ, Bm-rbIFNτ (10
ng/ml) significantly promoted development to the
expanded blastocyst stage. In conclusion, Bm-rbIFNτ was suggested to have the same
bioactivity as native IFNτ.

Abstract
Cytokines are thought to regulate prostaglandin (PG) secretion in the bovine endometrium. However, there is no consensus about the role of interleukin-1α (IL1A) on PG secretion. The objective of this study was to examine the influence of IL1A on basal and interferon-τ (IFNT)-regulated PGin vitrosecretion, as well its effects on PG secretion, progesterone (P4) output, and corpus luteum (CL)in vivolifespan. Explants of bovine endometrium (days 16–17 of the estrous cycle or early pregnancy) were stimulated with IL1A (10 ng/ml), IFNT (30 ng/ml), or IL1A combined with IFN. IL1A alone strongly stimulated luteotrophic PGE2secretion by endometrial tissues of both pregnant and nonpregnant cows. IL1A also stimulated luteolytic PGF2αoutput in the late luteal phase. IFNT augmented the stimulatory effect of IL1A on PGE2secretion. In anin vivoexperiment, saline or IL1A at different doses (0.001–10 μg/per animal) was applied to the uterine lumen on day 16 of the cycle. Only the highest dose of IL1A caused a temporal increase in PGF2αsecretion, while it had no effect on P4secretion or CL lifespan. Application of 0.1 and 1 μg IL1A stimulated P4and PGE2output and prolonged the CL lifespan. Although IL1A may stimulatein vitroluteolytic PGF2αsecretion during the estrous cycle, it only acts as a luteotrophic factorin vivo. IL1A increased luteotrophic PGE2and P4output, inhibiting spontaneous luteolysis. These luteotrophic effects may result in appropriate luteal development and function in cows during the estrous cycle and early pregnancy.

Abstract
A radioimmunoassay (RIA) was developed for quantification of bovine interferon (bIFN) tau, conceptus secretory protein, which allows for the maintenance of the corpus luteum during early pregnancy. A cDNA coding bIFN tau was derived from cultured trophoblast cells (TBs). Recombinant (r) bIFN tau was produced in a baculovirus expression system with two different viruses. The RIA was a double-antibody competitive binding assay that used anti-bIFN tau antiserum (raised in rabbits) as the primary antibody, a radioiodinated derivative of bIFNtau as the radioactive tracer, and goat anti-rabbit IgG as the secondary antibody. The antibody did not cross-react with rbIFN alpha, recombinant human IFN beta or recombinant ovine IFN tau. The correct recovery of amounts of rbIFN tau indicated good accuracy. Serially concentrated TB conditioned media, paralleled the standard curve for bIFN tau. The intra-assay and inter-assay coefficients of variation at bIFN tau levels of 7.8 and 15.6 ng/mL were 7.1 and 8.1%, and 11.0 and 8.5%, respectively. bIFN tau was directly detected in uterine flushings obtained from cows at Day 16 of pregnancy. In summary, this assay was suitable for the measurement of bIFN tau.

Abstract
We developed a procedure for the large-scale purification of bovine interferon-tau (boIFN-tau) by means of a silkworm-baculovirus gene expression system. Recombinant boIFN-tau (rboIFN-tau) was efficiently produced in the silkworm infected with boIFN-tau cDNA recombinant baculovirus and accumulated in the haemolymph. To establish a purification method suitable for mass production, we tried three crude purification methods, namely, an acidification and neutralization treatment (ANT), silica gel column chromatography (SGCC), and Blue sepharose column chromatography (BSCC) with a combination of Q-sepharose (QSC) and chelating sepharose column chromatographies (CSCC). As a result, the acidification and neutralization treatment was found to be the most efficient and cost effective. With this combination, we obtained 91% pure products. To confirm the applicability of the procedure for mass production, we inoculated 100 silkworms with the recombinant virus, and recovered about 4.55 mg (1.26 x 10(8)U/mg) of 91% pure rboIFN-tau by means of a combination of the ANT, followed by QSC and CSCC.
