Cathepsins: Novel opportunities for antibody therapeutics in cancer.

Cathepsins, the most abundant lysosomal proteases, have key functions in cell maintenance and homeostasis. They are overexpressed and hypersecreted in cancer and associated with poor prognosis. Secreted cathepsins display pro-tumour activities in the tumour microenvironment and thus represent interesting molecular targets in oncology.

Antibodies against the multifaceted cathepsin D protein open new avenues for TNBC immunotherapy.

Triple-negative breast cancer (TNBC) is a heterogeneous breast cancer subtype characterized by aggressive clinical behavior and poor prognosis. The immune landscape associated with TNBC often reveals high immunogenicity. Therefore, immunotherapy, which has demonstrated its efficacy in different cancer types, could be a promising strategy for TNBC, given the limited therapeutic options currently available besides conventional chemotherapy.

Infections in Kidney Transplant Recipients: Perspectives in French Caribbean.

Few studies have focused on the infectious complications in kidney transplant recipients in tropical regions, particularly in the Caribbean. The primary objective of this study was to determine the incidence of bacterial, fungal, and parasitic infections in kidney transplant recipients in the French Caribbean and French Guiana. We included all patients who received a kidney transplant at the University Hospital of Guadeloupe between January 2014 and October 2016, with post-transplant follow-up in the French Caribbean.

Prognostic value of tertiary lymphoid structures in triple-negative breast cancer: integrated analysis with the tumor microenvironment and clinicopathological features.

Background: In triple-negative breast cancer (TNBC), the most immunogenic breast cancer type, tumor-infiltrating lymphocytes (TILs) are an independent prognostic factor. Tertiary lymphoid structures (TLS) are an important TILs source, but they are not integrated in the current prognostic criteria.

Methods: In this retrospective study, TLS were assessed in hematein-eosin-saffron-stained (HES) histological sections from 397 early, chemotherapy-naive TNBC samples after primary surgical resection.
