A 100 plaque forming unit (pfu) dose of a temperature-sensitive (ts) mutant of vesicular
stomatitis
virus (VSV), tsG31 KS5, engendered a slowly progressive paralytic central nervous system (CNS) disease that killed all BALB/c nude mice within 28 days. Reconstitution of nude mice with 10(7) syngeneic splenocytes 24 h before intracerebral inoculation with tsG31 KS5 VSV, however, protected 92% of the animals from death. When these reconstituted animals were injected intracerebroventricularly with 14 pmol of
beta-endorphin
24 h after reconstitution with splenocytes and 24 h before inoculation with tsG31 KS5 VSV, only 72% of the animals survived. Furthermore, whereas 40% of the afflicted reconstituted nude mice given intracerebroventricular injections of sterile water were able to recover from the symptoms of disease, those surviving animals which received
beta-endorphin
were unable to do so. A single intravenous injection of 14 pmol
beta-endorphin
, or repeated postinfection administration of 28 pmol of
beta-endorphin
intravenously into nude mice reconstituted with syngeneic splenocytes, which were pretreated with
beta-endorphin
, did not alter the course of CNS disease induced by tsG31 KS5 VSV. The effect induced by intracerebroventricular injection of
beta-endorphin
was antagonized by naloxone, but not by the neuropeptide fragment
beta-endorphin
-(1-27). A simultaneous intracerebroventricular injection of reconstituted nude mice with 1220 pmol of naloxone and 14 pmol of
beta-endorphin
resulted in a 89% survival rate, and 33% of the afflicted animals were able to overcome the symptoms of the disease induced by tsG31 KS5 VSV. Intracerebroventricular injection of reconstituted nude mice with 330 pmol of
beta-endorphin
-(1-27) and 14 pmol of
beta-endorphin
resulted in a 72% survival rate and the surviving animals were unable to improve appreciably the clinical status of their disease. Injection of reconstituted nude mice with either 1220 pmol of naloxone or 330 pmol of
beta-endorphin
-(1-27) alone did not alter the course of the CNS disease in any way. A single intracerebroventricular injection of 29 pmol of another psychoactive peptide, [Des-Tyr]-endorphin, 24 h after reconstitution of nude mice with splenocytes and 24 h prior to infection with virus, resulted in 74% survival; and 39% of the afflicted animals were able to recover from the clinical symptoms.

A single intracerebroventricular injection of 100 ng of
beta-endorphin
altered the course of the central nervous system (CNS) infection of a temperature-sensitive mutant of vesicular
stomatitis
virus (VSV), tsG31-KS5. When mice were administered
beta-endorphin
and then 24 h later infected intracerebrally with tsG31-KS5 VSV, 70% of the animals died within 8 days of infection. In comparison, less than 10% of the animals had died after 21 days when infected with tsG31-KS5 VSV alone. When mice were injected with
beta-endorphin
and tsG31-KS5 VSV simultaneously, or with
beta-endorphin
21 days after infection, the more aggressive clinical disease was not observed. Superficially, the more lethal disease induced by
beta-endorphin
appeared to be a result of a mild hypothermia caused by the neuropeptide. beta-Endorphin, however, did not influence the disease in nude (nu/nu) mice even though their core temperatures were reduced to an extent similar to that of BALB/c (+/+) mice, implicating the involvement of T lymphocytes in the alteration of the course of infection in normal mice.

The mouse pituitary cell line, AtT-20, packages the
adrenocorticotropic hormone (ACTH)
in secretory vesicles and releases it when the cell is stimulated with secretagogues. These cells have the capacity, after transfection with the appropriate DNA, to package heterologous peptide hormones into the regulated secretory vesicles (Moore, H. P. H., M. D. Walker, F. Lee, and R. B. Kelly, 1983, Cell, 35:531-538). To test if other secreted proteins prefer a different route to the surface, we have transfected AtT-20 cells with DNAs coding for a fragment of a membrane protein, the vesicular
stomatitis
virus G protein from which the membrane spanning domain has been deleted (Rose, J. K., and J. E. Bergmann, 1982, Cell, 17:813-819). We found that the secreted vesicular
stomatitis
virus G proteins were not transported to the regulated secretory vesicles. Instead they preferentially exited the cell by the constitutive pathway previously found in these cells (Gumbiner, B., and R. B. Kelly, 1982, Cell, 28:51-59). In contrast, human growth hormone transfected into the cells by the same procedure was transported to the regulated pathway with a similar efficiency as the endogenous hormone ACTH. Transport of the secreted G protein to the regulated pathway, if it occurs at all, is at least 30-fold less efficient than peptide hormones. We conclude that the transport machinery in AtT-20 cells must selectively recognize different secreted proteins and sort them into distinct secretory pathways.

A panel of long-term murine T lymphocyte clones specific for the glycoprotein of vesicular
stomatitis
virus (VSV) in association with either H-2I-Ad or I-E(d) was tested for the production of cytokines in both resting and poststimulation states using both in situ hybridization and bioassay. All but one of the clones showed antigen-specific cytolytic activity in a 4-hr 51Cr release assay. Unexpectedly, the clones did not appear to be typical Th1 cells. Five of these T cell clones produced both IL-2 and IFN-gamma but not IL-4 after stimulation with either phorbol 12-myristate 13-acetate (PMA) or concanavalin A (Con A). Some clones constitutively expressed mRNA for IL-2 and INF-gamma. The proliferation of these clones was factor independent, suggesting an autocrine growth mechanism. Three clones produced variable levels of IL-4 mRNA and some, to significant quantities, of IL-2 mRNA. One cytolytic clone produced neither IL-2 nor IL-4 mRNA to detectable levels, although mRNA for IFN-gamma was observed. A noncytolytic, Ag-specific clone produced IL-6, tumor necrosis factor (TNF), and lymphotoxin (LT), but no IL-2, IL-4, or IFN-gamma mRNA. There was a strong quantitative correlation between the expression of IL-2-, INF-gamma-, and LT-specific mRNAs by the clones. All the T cell clones tested which secreted INF-gamma and LT expressed no measurable IL-4 mRNA. We examined expression of several other genes in the panel of clones. These included TNF,
met-enkephalin
(met-enk), IL-1, and IL-6. IL-1 m-RNA synthesis was not observed in any of the T cell clones. Almost all clones produced TNF mRNA. Parallel bioassays showed that secreted IL-2/IL-4 activity levels and mRNA levels correlated well for all clones. Thus, we observed a great degree of heterogeneity among CD4+ cytolytic T lymphocyte clones.

A single intracerebroventricular (i.c.v.) injection of 14 pmol of
beta-endorphin
into 6-7-week-old BALB/c (+/+) donor mice, 24 h prior to isolation of their T lymphocytes for use for reconstitution of athymic BALB/c (nu/nu) nude mice, altered the immuno-protective effect of adoptive transfer against an intracerebral (i.c.) infection with a temperature-sensitive mutant of vesicular
stomatitis
virus (tsG31 KS5 VSV). Simultaneous injection of
beta-endorphin
and naloxone into donor animals negated the opiate effects on splenic lymphocytes. T lymphocytes, isolated from
beta-endorphin
-treated donors, and then depleted with anti-asialo GM1 antiserum and complement failed to demonstrate the detrimental effects of
beta-endorphin
.
