RESUMO

INTRODUCTION: Studies examining profit suggest that former tobacco farmers do as well or better than current tobacco farmers. Research has yet to examine the relationship among current and former tobacco farmers, poverty, and receipt of government social assistance. This type of research is critical to understanding the direct and indirect subsidization of tobacco growing. This study analyzed tobacco farmers' poverty levels and receipt of government social assistance programs. METHODS: We designed and conducted an original four-wave economic survey of current and former tobacco farming households in Indonesia between 2016 and 2022. We then used descriptive analysis and probit regression for panel data to estimate the relationship between tobacco farming and poverty status. RESULTS: Tobacco farmers' per capita income and poverty rates vary across years. The poverty rate was significantly higher in the year with a higher-than-normal rainfall as it negatively affected farming outcomes. During this year, the poverty rate among current tobacco farmers was also higher than that of former tobacco farmers. Regression estimates from the panel data confirm the association between tobacco farming and the likelihood of being poor. We also found a high share of current tobacco farmers who receive government social assistance programs, such as cash transfer programs and a universal healthcare program. CONCLUSIONS: Our findings show high poverty rates-particularly during bad farming years-and high rates of government social assistance among tobacco farmers. The high rates of government assistance among tobacco farmers living in poverty show that the government is indirectly subsidizing the tobacco industry.

RESUMO

Regulatory T (Treg) cells are important in maintaining self-tolerance and immune homeostasis. The Treg cell transcription factor Foxp3 works in concert with other co-regulatory molecules, including Eos, to determine the transcriptional signature and characteristic suppressive phenotype of Treg cells. Here, we report that the inflammatory cytokine interleukin-6 (IL-6) actively repressed Eos expression through microRNA-17 (miR-17). miR-17 expression increased in Treg cells in the presence of IL-6, and its expression negatively correlated with that of Eos. Treg cell suppressive activity was diminished upon overexpression of miR-17 in vitro and in vivo, which was mitigated upon co-expression of an Eos mutant lacking miR-17 target sites. Also, RNAi of miR-17 resulted in enhanced suppressive activity. Ectopic expression of miR-17 imparted effector-T-cell-like characteristics to Treg cells via the de-repression of genes encoding effector cytokines. Thus, miR-17 provides a potent layer of Treg cell control through targeting Eos and additional Foxp3 co-regulators.
