The area of wound healing presents a promising field of interest for clinicians as well as the scientific community. A major concern for physicians is the rising number of elderly people suffering from diabetes, leprosy, tuberculosis and the associated chronic wounds. While traditional therapies target basic wound care, innovative strategies that accelerate wound healing are needed.

Co-inhibitory molecules, such as cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1 (PD-1), known as immune checkpoints, regulate the activity of T and myeloid cells during chronic viral infections and are well-established for their roles in cancer therapy. However, their involvement in chronic bacterial infections, particularly those caused by pathogens endemic to developing countries, such as Mycobacterium tuberculosis (Mtb), remains incompletely understood. Cytokine microenvironment determines the expression of co-inhibitory molecules in tuberculosis: Results indicate that the cytokine IL-12, in the presence of Mtb antigens, can enhance the expression of co-inhibitory molecules while preserving the effector and memory phenotypes of CD4+ T cells.

January 2025
Department of Neurology, the First Affiliated Hospital of Chongqing Medical University, Chongqing, People's Republic of China.
Context: This study aimed to investigate the characteristics, diagnosis, and management of tuberculous longitudinally extensive transverse myelitis (TB-LETM), a rare manifestation of tuberculosis.
Findings: We analyzed two rare cases of TB-LETM and discussed their clinical manifestations and imaging findings in the context of the relevant literature. Patient 1, a 23-year-old female, presented with quadriplegia and dysuria, and spinal magnetic resonance imaging (MRI) revealed lesions extending from C1 to T3.

Copper is a vital trace element crucial for mediating interactions between and macrophages. Within these immune cells, copper modulates oxidative stress responses and signaling pathways, enhancing macrophage immune functions and facilitating clearance. Conversely, copper may promote escape from macrophages through various mechanisms: inhibiting macrophage activity, diminishing phagocytic and bactericidal capacities, and supporting survival and proliferation.

Vasculitis is a group of uncommon diseases characterized by inflammation of blood vessels, which contributes to the organ ischemia and damage. Cigarette smoke contains a high concentration of various toxins, which have the potential to affect the immune response and development of autoimmune/autoinflammatory rheumatic diseases including vasculitis. Smoking influences both innate and adaptive immune systems and plays binary functions in modulating immunity by either aggravating pathogenic immune responses or attenuating defensive immunity.
