Protective immune responses to (Mtb) infection substantially depend on a delicate balance within cytokine networks. Thus, immunosuppressive therapy by cytokine blockers, as successfully used in the management of various chronic inflammatory diseases, is often connected with an increased risk for tuberculosis (TB) reactivation. Hence, identification of alternative therapeutics which allow the treatment of inflammatory diseases without compromising anti-mycobacterial immunity remains an important issue. On the other hand, in the context of novel therapeutic approaches for the management of TB, host-directed adjunct therapies, which combine administration of antibiotics with immunomodulatory drugs, play an increasingly important role, particularly to reduce the duration of treatment. In both respects, cytokines/cytokine receptors related to the common receptor subunit gp130 may serve as promising target candidates. Within the gp130 cytokine family, interleukin (IL)-6, IL-11 and IL-27 are most explored in the context of TB. This review summarizes the differential roles of these cytokines in protection and immunopathology during Mtb infection and discusses potential therapeutic implementations with respect to the aforementioned approaches.

Tuberculous meningitis (TBM), a severe form of non-purulent meningitis caused by (Mtb), is the most critical extrapulmonary tuberculosis (TB) manifestation, with a 30-40% mortality rate despite available treatment. The absence of distinctive clinical symptoms and effective diagnostic tools complicates early detection. Recent advancements in nucleic acid detection, genomics, metabolomics, and proteomics have led to novel diagnostic approaches, improving sensitivity and specificity.

Methods: Using a TB household contact (HHC) study design among 130 Ugandan children less than 5 years with established -exposure, we compared the usefulness of the tuberculin skin test (TST) and QuantiFERON Gold Plus (QFT-Plus) to identify children with evidence for -sensitization.
Although granulomatous interstitial nephritis (GIN) is a rare histological finding in kidney transplants, the joint occurrence of GIN and focal segmental glomerulosclerosis (FSGS) has not, to our knowledge, been reported in the literature. We report a case of GIN and de novo FSGS in kidney transplant recipients leading to allograft failure. A 69-year-old male with a history of end-stage renal disease (ESRD) of unknown etiology, as well as liver failure from hepatitis B and C co-infection, initially had a living unrelated kidney transplant (LURT) in 2007 and subsequently received both liver and kidney transplants (SLKTs) in 2017.

The 2'-5' oligoadenylate synthetase (OAS)family, comprising OAS1, OAS2, OAS3, and OASL, has been shown to participate in the host immune response against Mycobacterium tuberculosis (Mtb). However, their expression profiles in tuberculosis (TB) remain inconsistent. In two TB-related datasets, the OAS family exhibits contrasting expression trends.

Infection with HIV is associated with dysregulated CD4 T cell responses to Mycobacterium tuberculosis (Mtb) and increased risk of developing tuberculosis. Mtb-specific CD4 T cells in people with HIV have diminished Th1 cytokine production capacity, thus we utilized a flow cytometry-based assay to measure CD40L expression by Mtb-specific CD4 T cells in a cytokine-independent manner. We evaluated the frequency and phenotype of Mtb-specific CD4 responses in Kenyan adults with latent Mtb infection and found that the majority of Mtb-specific CD4 T cells expressed CD40L in the absence of IFN-γ, regardless of HIV infection status.
