Triple-negative breast cancer (TNBC) is a challenging subtype of breast cancer characterized by the absence of estrogen and progesterone receptors and HER2 expression, leading to limited treatment options and a poorer prognosis. TNBC is particularly prevalent in premenopausal African-descent women and is associated with aggressive tumor behavior and higher metastatic potential. Tumor-associated macrophages (TAMs) are abundantly present within the TNBC microenvironment and play pivotal roles in promoting tumor growth, progression, and metastasis through various mechanisms, including immune suppression and enhancement of angiogenesis. This review provides an in-depth overview of TNBC, focusing on its epidemiology, its molecular characteristics, and the critical influence of TAMs. It discusses the pathological and molecular aspects that define TNBC’s aggressive nature and reviews current and emerging therapeutic strategies aimed at targeting these dynamics. Special attention is given to the role of TAMs, exploring their potential as therapeutic targets due to their significant impact on tumor behavior and patient outcomes. This review aims to highlight the complexities of the TNBC landscape and to present the innovative approaches that are currently being pursued to improve therapeutic efficacy and patient survival.

Our ability to remain in good health, both physical and mental, largely depends on the amount of time we spend out of doors. Certain changes to our lifestyle which came about due to technological progress have reduced the frequency of direct contact with the natural world and resulted in people remaining indoors for around 90% of their time. This has a negative impact on our health due to prolonged exposition to indoor pollutants, including light pollution on account of artificial lighting. A reasonable conclusion can be drawn that members of developed societies will, in the nearest future, continue to spend most of their time in various enclosed spaces. Because of this, in addition to taking steps aimed at motivating people to spend as much time as possible outside, we need to ensure that the conditions indoors are detrimental to us to the least extent possible and that the structural design of rooms where we stay supported our biological and mental needs.

In 2024, the United States was projected to experience 2 million new cancer diagnoses and approximately 611,720 cancer-related deaths, reflecting a broader global trend in which cancer cases are anticipated to exceed 35 million by 2050. This increasing burden highlights ongoing challenges in cancer treatment despite significant advances that have reduced cancer mortality by 31% since 1991. Key obstacles include the disease’s inherent heterogeneity and complexity, such as treatment resistance, cancer stem cells, and the multifaceted tumor microenvironment (TME). The TME—comprising various tumor and immune cells, blood vessels, and biochemical factors—plays a crucial role in tumor growth and resistance to therapies. Recent innovations in cancer treatment, particularly in the field of immuno-oncology, have leveraged insights into TME interactions. An emerging example is the FDA-approved therapy using tumor-infiltrating lymphocytes (TILs), demonstrating the potential of cell-based approaches in solid tumors. However, TIL therapy is just one of many strategies being explored. This review provides a comprehensive overview of the emerging field of immuno-oncology, focusing on how novel therapies targeting or harnessing components of the TME could enhance treatment efficacy and address persistent challenges in cancer care.

Macrophages are key players in inflammation and immune responses due to their phenotypic plasticity. This study examined the effects of pooling donor-derived macrophages on their phenotype and function, focusing on murine bone marrow-derived macrophages (BMDMs) and human monocyte-derived macrophages (hMDMs). Murine BMDMs were generated using L929-conditioned media and compared across single and pooled donors (two-to-five mice). Similarly, hMDMs cultured with M-CSF from individual donors were compared to pooled cultures. Pooling macrophages did not alter core phenotypic markers (CD11b, F4/80, CD64) or functional outputs such as cytokine secretion and nitric oxide production. In hMDMs, pooling reduced variability and led to slightly elevated or more-uniform marker expression. These findings demonstrate that pooling macrophages minimizes inter-individual variability without compromising cellular stability or function, enhancing reproducibility in immunological research while maintaining the option of single-donor studies for personalized analyses.

Today, science and medicine are striving to develop novel techniques for treating deadly diseases, including a wide range of cancers. Efforts are being made to better understand the molecular and biochemical mechanisms of tumor cell functioning, but a particular emphasis has recently been given to investigating immune cells residing in the tumor microenvironment, which may lead to revolutionary benefits in the design of new immunotherapies. Among these cells, tumor-associated macrophages (TAMs) are highly abundant and act as critical regulators of ovarian cancer progression, metastasis, and resistance to therapy. Their dual nature—as drivers of malignancy and as potential therapeutic mediators—has positioned them at the forefront of research into next-generation immunotherapies. As therapeutic targets, approaches include blocking macrophage recruitment (e.g., CSF-1/CSF-1R inhibitors), selectively depleting subsets of TAMs (e.g., via Folate Receptor Beta), or reprogramming immunosuppressive M2-like macrophages toward an anti-tumor M1 phenotype. On the other hand, macrophages can also serve as a therapeutic tool—they may be engineered to enhance anti-tumor immunity, as exemplified by the development of Chimeric Antigen Receptor Macrophages (CAR-Ms), or leveraged as delivery vehicles for targeted drug transport into the tumor microenvironment. A particularly innovative strategy involves Macrophage–Drug Conjugates (MDCs), which employs the transfer of iron-binding proteins (TRAIN) mechanism for precise intracellular delivery of therapeutic agents, thereby enhancing drug efficacy while minimizing systemic toxicity. This review integrates current knowledge of TAM biology, highlights emerging therapeutic approaches, and underscores the promise of macrophage-based interventions in ovarian cancer. By integrating macrophage-targeting strategies with advanced immunotherapeutic platforms, novel treatment paradigms may be determined that could substantially improve outcomes for patients with ovarian cancer and other solid tumors. Our work highlights that macrophages should be a particular area of research interest in the context of cancer treatment.

The expectation of effective detection of perpetrators of crimes is fundamental for every person, given their deep-seated need to feel safe. In the context of modern realities, it is difficult to imagine effective activities of the police, prosecutor’s office or judiciary without the use of advanced, reliable forensic techniques. The aim of this publication was to collect and present highlights of the evolution in forensic research based on a variety of scientific specializations, including forensic microbiology, forensic entomology, forensic botany, and soil science.
