Incidence of chronic stress in response to T-cell treatment in patients with serous ovarian cancer.

The research was conducted between Ponce Health Sciences University and Duke University.

Patients face a surge in cancer hormones around the time of receiving a positive diagnosis of cancer. Tension This leads to altered psychological states, as confirmed by research conducted by Ponce Health Sciences University and Duke University.

Therefore, this group of researchers found that Tension Affects the functioning of T-cell treatment in chronic patients ovarian cancer High-grade serous, a fact that alters the healing process in patients and which in the opinion of physicians may negatively affect the outcome.

“Our team’s work shows that Tension Chronic disease promotes a greater inflammatory response”, as they noted in their research, which includes that preliminary data show altered proportions of T cells and a skewed expression of markers of fatigue in patients. ovarian cancer High grade serous (HGSOC).

There are total 66 patients ovarian cancer high-grade serous tissue for people who measure cytokine levels, indicating that Tension This significantly affects the tumor.

In the paper they indicate that inflammatory cytokines in chemoresistant and recurrent tumors, identified as eotaxin, IL-6 and IL-7, are what induce these patients’ body changes.

In the metanephrine test, which measures the levels of substances called metanephrine and normetanephrine in the blood, the researchers found that these were positively correlated with protumoral and inflammatory cytokines identified as SCD40L, FGF-2, and MIP1a.

On the other hand, CD8+ T cells obtained from epinephrine-treated ascites showed decreased co-expression of CD38 and granzyme B, indicating, the authors state, a role for hormones. Tension suppressing T cell activity.

From which they conclude that:

*Chemoresistant and recurrent tumors were associated with increased proinflammatory cytokines.

*Higher metanephrine levels were correlated with higher protumor cytokines.

*Epinephrine stimulation reduced the function of CD8+ T cells in patients with ascites ovarian cancer high grade serous

In summary, these suggest a role for the data Tension in immunosuppression and may affect the efficacy of therapies that aim to restore T-cell function.

The National Cancer Institute indicates that in this therapy, doctors perform T-cell transfers, a type of immunotherapy that helps the immune system fight cancer better.

The same institution states that there are two main types of T-cell transfer therapy: tumor-infiltrating lymphocyte therapy (or TIL) and CAR T-cell therapy. In both types of therapy, a sample of immune cells is obtained, large numbers of these cells are grown in the laboratory, and then these cells are returned to the patient via an infusion.
