The gut microbiome modulates immunotherapy treatment responses, and this may explain why immune checkpoint inhibitors, such as anti-PD-1, are only effective in some patients. Previous studies correlated lipopolysaccharide (LPS)-producing microbes with poorer prognosis; however, LPS from diverse bacterial species can range immunostimulatory to inhibitory. Here, by functionally analysing faecal metagenomes 112 patients melanoma, we found that a subset of LPS-producing bacteria encoding...
Abstract CD4 + regulatory T (Treg) cells, dependent upon the transcription factor Foxp3, contribute to tumour immunosuppression but are also required for immune homeostasis. There is interest in developing therapies that selectively target immunosuppressive function of Treg cells within tumours without disrupting their systemic anti‐inflammatory function. High levels expression chemokine (C‐C motif) receptor 8 (CCR8) discriminate from those found lymphoid tissues. It has recently been...
Cytokines interact with their receptors in the extracellular space to control immune responses. How physicochemical properties of influence cytokine signaling is incompletely elucidated. Here, we show that activity interleukin-2 (IL-2), a critical T cell immunity, profoundly affected by pH, limiting IL-2 within acidic environment tumors. Generation lactic acid tumors limits STAT5 activation, effector differentiation, and antitumor immunity CD8

Women with BRCA1 or BRCA2 germline mutations have an elevated risk of developing breast and/or ovarian cancer. Because the early onset disease, screening this group women should start at earlier age than in general population. The association magnetic resonance imaging (BMRI) and ultrasonography (US) mammography (MX) clinical examination (CBE) regular surveillance these individuals has been proposed seems to improve detection cancer.Within a multicenter study started by Istituto Superiore di...
Abstract Immune checkpoint inhibitors (ICI), such as anti-PD-1, have revolutionized cancer treatment, but they are only effective for a minority of patients. The gut microbiome plays crucial role in modulating immunotherapy treatment responses, and previous studies correlated lipopolysaccharide (LPS)-producing microbes with poorer prognosis. However, LPS from diverse bacterial species activities ranging immunostimulatory to inhibitory. By functionally analyzing fecal metagenomes 112 melanoma...
