In this task, you're given a paragraph from the research paper and your task is to generate a suitable title for the research paper based on the given paper. Under 100 words is a good title length.

Example Input: Chronic infection and cancer are associated with suppressed T cell responses in the presence of cognate antigen. Recent work identified memory-like CXCR5 + TCF1 + CD8 + T cells that sustain T cell responses during persistent infection and proliferate upon anti-PD1 treatment. Approaches to expand these cells are sought. We show that blockade of interferon type 1 (IFN-I) receptor leads to CXCR5 + CD8 + T cell expansion in an IL-27-and STAT1-dependent manner. IFNAR1 blockade promoted accelerated cell division and retention of TCF1 in virus-specific CD8 + T cells. We found that CD8 + T cell-intrinsic IL-27 signaling safeguards the ability of TCF1 hi cells to maintain proliferation and avoid terminal differentiation or programmed cell death. Mechanistically, IL-27 endowed rapidly dividing cells with IRF1, a transcription factor that was required for sustained division in a cell-intrinsic manner. These findings reveal that IL-27 opposes IFN-I to uncouple effector differentiation from cell division and suggest that IL-27 signaling could be exploited to augment self-renewing T cells in chronic infections and cancer.
Example Output: IL-27 promotes the expansion of self-renewing CD8 + T cells in persistent viral infection

Example Input: Background: The development of a protective vaccine against canine visceral leishmaniasis (CVL) is an alternative approach for interrupting the domestic cycle of Leishmania infantum. Given the importance of sand fly salivary proteins as potent immunogens obligatorily co-deposited during transmission of Leishmania parasites, their inclusion in an anti-Leishmania vaccine has been investigated in the last few decades. In this context, we previously immunized dogs with a vaccine composed of L. braziliensis antigens plus saponin as the adjuvant and sand fly salivary gland extract (LBSapSal vaccine). This vaccine elicited an increase in both anti-saliva and anti-Leishmania IgG isotypes, higher counts of specific circulating CD8 + T cells, and high NO production. Methods: We investigated the immunogenicity and protective effect of LBSapSal vaccination after intradermal challenge with 1 × 10 7 late-log-phase L. infantum promastigotes in the presence of sand fly saliva of Lutzomyia longipalpis. The dogs were followed for up to 885 days after challenge. Results: The LBSapSal vaccine presents extensive antigenic diversity with persistent humoral and cellular immune responses, indicating resistance against CVL is triggered by high levels of total IgG and its subtypes (IgG1 and IgG2); expansion of circulating CD5 + , CD4 + , and CD8 + T lymphocytes and is Leishmania-specific; and reduction of splenic parasite load. Conclusions: These results encourage further study of vaccine strategies addressing Leishmania antigens in combination with proteins present in the saliva of the vector.
Example Output: LBSapSal-vaccinated dogs exhibit increased circulating T-lymphocyte subsets (CD4 + and CD8 + ) as well as a reduction of parasitism after challenge with Leishmania infantum plus salivary gland of Lutzomyia longipalpis

Example Input: Objectives: The aims of this article were: to summarize the pharmacology, pharmacokinetics, and efficacy of daptomycin; to explore its safety profile', and to discuss its current and potential roles as an antimicrobial therapy Results: Phase III study results suggest no difference in efficacy or tolerability between daptomycin 4 mg/kg IV QD and vancomycin or semisynthetic penicillins for complicated skin and skin-structure infections. Animal studies suggest daptomycin may be useful for the treatment of endocarditis. Daptomycin is not indicated for pneunionia, with poorer outcomes than conventional treatnient. It is available as an IV niedication and exhibits 92% plasnia protein binding in vitro. In healthy adult humans, daptoniycin has a volume of distribution of 0.1 Ukg and a plasma elimination half-life of -9 hours, and is eliminated primarily by renal excretion (-54%). In patients with reduced renal function, including those receiving hemodialysis and peritoneal dialysis, the dose interval should be 48 hours. No dosage adjustnient appears to be necessary for mild to nioderate hepatic impairnient. The use of daptomycin in patients with severe hepatic irnpairnient has not been assessed. The niost comnionly reported adverse events include constipation, nausea, injection-site reactions, headache, and diarrhea. Patients should also be nionitored regularly for skeletal niuscle toxicity. Conclusions: Daptoniycin may be useful for complicated skin and skin-structure infections and gram-positive pathogens resistant to conventional antimicrobials. However, limited data are currently available for duration of treatment beyond 14 days and at doses >4 mg/kg QD. (Clin Ther.
