From June 1986 to November 1989, 7 patients (pts.) with transitional bladder cancer were treated with CDDP 70 mg/m2 i.v. on day 1 and MTX 40 mg/m2 i.v. on days 8 and 15. The initial stage was T2 N0 M0 (2), T2 N0 M0 (8), T4 N0 M0 (4) and T3-4 N+ M0 (3). The median age was 56 years. After a median number of two cycles (1-5) of CDDP-MTX, 3/17 pts. (17.6%) had a complete remission (CM), 9/17 pts. (53%) a partial response (PR) greater than 50%, 4/17 pts. (23.4%) a PR less than 50%, 1/17 pts. (6%) a stable disease. Nausea and vomiting occurred in almost all pts., 20% of pts. had grade 3 stomatitis, 35% of pts. had diarrhoea, 20% of pts. had conjunctivitis, 7% of pts. had a bone marrow depression and hair loss. One patient had severe renal and liver toxicity and grade 4 bone marrow suppression with sepsis, completely controlled after intensive care. The treatment after neoadjuvant chemotherapy was: radical cystectomy (11)- in one following radiotherapy -; partial resection + lymphoadenectomy (2); TUR (4) in 1 pt. with lymphoadenectomy. After a median follow-up of 28 months (6-36), 12/17, equivalent to 71% of pts. are disease free, 3/17 (17%) are alive with disease, 2/17 (12%) died. In conclusion the association of neoadjuvant CDDP-MTX can induce a high percentage of response, and can preserve bladder function in some patients. Further controlled trials and a longer follow-up are needed to better define the exact role of this combination in terms of disease free survival, total survival and quality of life.

CCC/2M, CCC/10Y and CCC/MT-2 cat kidney cells producing Japanese isolates of human T-cell leukemia virus type I (HTLVs) and HOS/PL human osteosarcoma cells producing an American isolate of HTLV were infected with vesicular stomatitis virus (VSV) to prepare VSV pseudotypes bearing envelope antigens of HTLVs. VSV propagated in CCC/2M cells contained plaque-forming fractions that were not neutralized by treatment with anti-VSV serum alone: VSV pseudotypes bearing envelope antigens of HTLV2M and CCC cat endogenous virus were formed by infection of CCC/2M cells with VSV. Japanese HTLV2M, HTLV10Y and HTLVMT-2 and American HTLVPL pseudotypes were neutralized by sera of Japanese, American and British patients with ATL. Each serum, including the serum of the patient from whom HTLV2M or HTLV10Y had been derived, gave similar antibody titers against Japanese and American HTLV pseudotypes. The HTLV pseudotypes were also neutralized by rabbit serum raised against HTLVMT-2. A rabbit antiserum against the C-terminal half of the HTLV env protein produced in E. coli also neutralized Japanese and American HTLV pseudotypes. Thus, VSV pseudotype analyses indicated that envelope antigens of HTLVs represent a single serotype worldwide. The env protein produced in E. coli may be used to raise neutralizing antibody against HTLVs.

We tried to transmit human T-cell leukemia virus type I (HTLV-I) into non-lymphoid cells and found that S+L- CCC cat cells were permissive for HTLV-I. Using these HTLV-positive cat cells, vesicular stomatitis virus (VSV) pseudotypes bearing envelope antigens of Japanese isolates of HTLVs were prepared and their reactivities with human or rabbit serum were examined. Japanese HTLV2M, HTLV10Y, and HTLVMT-2 pseudotypes and American HTLVPL pseudotype were neutralized by sera of Japanese and American patients with adult T-cell leukemia/lymphoma (ATL) and rabbit antisera against HTLV. Each serum showed similar antibody titers against different pseudotypes. Thus, envelope antigens of four HTLVs that reacted with the human and rabbit sera were considered to belong to a single serotype.

The replication of feline leukemia virus (FeLV) is inhibited by treatment of cat cell cultures with crude human leukocyte interferon (HuIFN-alpha) as evidenced by titration of the infectious progeny. The inhibition can be demonstrated in three different cell lines in which the production of hemagglutinin by encephalomyocarditis (EMC) virus, and plaque formation by vesicular stomatitis virus (VSV) are also inhibited by the HuIFN-alpha. The dose dependency of the inhibition of EMC virus by the HuIFN-alpha is similar to that obtained with feline interferon in each of the three cell lines. VSV and EMC virus are less than 10 times more sensitive than FeLV to the inhibitory action of HuIFN-alpha if responses to a single interferon treatment are compared for each of the viruses tested in the most sensitive cell line, FEA. The interferon effect on FeLV is more pronounced when it is added within one day after the inoculation of the cells rather than applied before cell infection. The induction of focus formation by FeLV can also be inhibited by HuIFN-alpha in cat cells (CCC-81) which contain the murine sarcoma virus genome.

We have developed a cell-free infection system to titrate neutralizing antibodies against human T-cell leukemia virus type 1 (HTLV-1) using the polymerase chain reaction (PCR). S+L-CCC (8C) feline kidney or U-251 MG human glioma cells were infected with a cell-free culture supernatant derived from HTLV-1-infected c77 feline cells. DNA was extracted from 8C or U-251 MG cells after incubation for 24 hr and amplified by PCR. The c77 cell supernatant gave discrete bands, whereas those of HTLV-1-positive T cells did not. When the inocula were treated with HTLV-1 antibody-positive human sera or the monoclonal or polyclonal antibody against the peptide 190-199 of HTLV-1 envelope protein gp46, the subsequent formation of HTLV-1 proviral DNA was inhibited. We determined the titers of neutralizing antibodies by densitometrically scanning the intensity of the PCR bands. These titers correlated well with those determined by the plaque assay using a pseudotype of vesicular stomatitis virus bearing the envelope antigens of HTLV-1. At high serum concentrations, many seronegative samples markedly inhibited the plating of the HTLV-1 pseudotype whereas they barely affected results obtained by PCR. Thus, the c77-PCR system can detect neutralizing antibodies against HTLV-1 even at low titers.
