Leishmaniasis is one of the main vectors borne and neglected tropical parasitic diseases. T cell cytokine responses are highly important in the presentations of disease such as control or progression, and understanding of the host immunological response is valuable in diagnosis, follow-up, and vaccine designs. In the current study, the profile of IFN-ɤ, TNF-α, and IL-10 cytokines was investigated through the ELISA technique in PBMCs isolated from antimony resistance and susceptible patients.

In this experimental study, 54 patients with healing (n=27) or non-healing (n=27) CL were recruited. Lesion samples were collected to determine the genotype of Leishmania spp. and peripheral blood mononuclear cells (PBMCs) were obtained to evaluate the cytokines profiles using soluble Leishmania antigen (SLA) and phytohaemagglutinin (PHA) mitogen. Cytokines were assessed by the ELISA technique

The IFN-ɤ and TNF-α cytokines were significantly increased in the healing group treated with both SLA antigen and PHA mitogen (P<0.001). The level of IL-10 was significantly increased in non-healing and significantly declined in healing groups (P<0.001).

The profile of IFN-ɤ, TNF-α, and IL-10 cytokines are crucially associated with the response of treatment.

The spread of infectious diseases and malignant diseases has been increasing in the recent years. The use of chemical drugs, in addition to the development of drug resistance, also cause serious side effects. We conducted the present study to examine the antibacterial, antiviral, and anti-cancer effects of E. camaldulensis as a herbal remedy.

We extracted E. camaldulensis using a hydroalcoholic solution. The antiviral effect of the plant was investigated at the time of the Herpes simplex virus entry and once the virus entered the cell. Moreover, we evaluated MIC and MBC of E. camaldulensis on Klebsiella pneumonia, Staphylococcus aureus, Streptococcus pyrogens, Streptococcus agalactiae, Acinetobacter baumannii, and Corynebacterium glutamicum. For the evaluation of cell cytotoxicity, HFF-2 (NCBI: C163) and A549 )ATCC: CCL81) cell lines were utilized.

The results of the cytotoxicity test indicated that both cell lines were sensitive to the hydroalcoholic extracts of E. camaldulensis. The MIC for A. baumannii, K. pneumonia, and C. glutamicum was 6.25 µg/ml, and the MIC for S. aureus, S. pyogenes, and S. agalactiae was 12.5 µg/ml. MBC was evaluated as 25 µg/ml for S. aureus, S. pyogenes, and S. Agalactiae. It was 12.5 µg/ml for A. baumannii, K. pneumonia, and S. Agalactiae. IC50 value on entering the virus into the cell was 40 µg/ml, and following the absorption of the virus, the IC50 value was 80 µg/ml.

The results of this study demonstrated that E. camaldulensis is of antibacterial, antiviral, and anti-cancer potentials and could be used as a candidate for the preparation of a new drug.
